Let's divide 42258921 by 365
We want to figure out the number of times 42258921 can be divided by 365.

Going ahead to step 1:
4 divided by 365 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 365

Moving on to step 2:
When dividing 42 by 365, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 365

Going ahead to step 3:
365 goes into 422 1 times with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 365 away from 422, we end up with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 365

Advancing to step 4:
The number 365 fits into 575 1 times, leaving a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 210 after subtracting 365 from 575.
Include the next digit (8) from the dividend after 210, then repeat: 2108 / 365

Advancing to step 5:
The number 365 fits into 2108 5 times, leaving a remainder of 283.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 1825 from 2108 to get 283.
Include the next digit (9) from the dividend after 283, then repeat: 2839 / 365

On to step 6:
365 can be fit into 2839 7 times, resulting in a remainder of 284.
Write down 7 as next digit of the result. 
Result so far: 1157.0
Deduct 2555 from 2839 and we're left with 284.
Grab the next digit (2) from the dividend, add it to 284, then carry on: 2842 / 365

Step 7:
The number 365 fits into 2842 7 times, leaving a remainder of 287.
The number 7 becomes the next digit in our result. 
Result so far: 11577.0
The remainder is 287 after subtracting 2555 from 2842.
Append the next digit (1) from the dividend to 287 and continue with: 2871 / 365

Advancing to step 8:
2871 divided by 365 is 7 with a remainder of 316.
Record the quotient 7 as the next digit in the result. 
Result so far: 115777.0
If we take 2555 away from 2871, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 9:
If we divide 3160 by 365, we get 8 and a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 115777.8
If we subtract 2920 from 3160, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
365 can be fit into 2400 6 times, resulting in a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 115777.86
The remainder is 210 after subtracting 2190 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 11:
2100 divided by 365 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 115777.865
Subtracting 1825 from 2100 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 12:
When dividing 2750 by 365, we get 7 with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 115777.8657
Subtracting 2555 from 2750 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 13:
365 can be fit into 1950 5 times, resulting in a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 115777.86575
If we subtract 1825 from 1950, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 14:
If we divide 1250 by 365, we get 3 and a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 115777.865753
Subtracting 1095 from 1250 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 15:
365 can be fit into 1550 4 times, resulting in a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 115777.8657534
Deduct 1460 from 1550 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
If we divide 900 by 365, we get 2 and a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 115777.86575342
Deduct 730 from 900 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 115777.86575342 with a remaining 1.7e-07.
