We're dividing 776590 by 42 
We want to figure out the number of times 776590 can be divided by 42.

Advancing to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 42

Advancing to step 2:
If we divide 77 by 42, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 77, we get 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 42

Let's proceed to step 3:
42 can be fit into 356 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 336 from 356 leaves us with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 42

Advancing to step 4:
If we divide 205 by 42, we get 4 and a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 168 from 205, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 42

On to step 5:
42 can be fit into 379 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1849.0
Subtracting 378 from 379 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 42

Let's proceed to step 6:
10 divided by 42 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 18490.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 18490.2
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 18490.23
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 18490.238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 18490.238
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 18490.23809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 18490.238095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 18490.2380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18490.23809523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 18490.23809523 and a remainder of 3.4e-08.
