Let's divide 422545 by 42
We want to figure out the number of times 422545 can be divided by 42.

Step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 42

Advancing to step 2:
When dividing 42 by 42, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 42 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 42

Moving on to step 3:
When dividing 2 by 42, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 42

Advancing to step 4:
42 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 42

Going ahead to step 5:
The number 42 fits into 254 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 1006.0
If we take 252 away from 254, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 42

Let's proceed to step 6:
When dividing 25 by 42, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 10060.0
The remainder is 25 after subtracting 0 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
42 goes into 250 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 10060.5
Deduct 210 from 250 and we're left 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.

Moving on to step 8:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 10060.59
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.

Let's proceed to step 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 10060.595
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10060.5952
If we take 84 away from 100, we end up 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 11:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 10060.59523
If we take 126 away from 160, we end up 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.

Moving on to step 12:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10060.595238
If we subtract 336 from 340, we 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 13:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10060.595238
Subtracting 0 from 40 leaves us 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.

Step 14:
42 goes into 400 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 10060.59523809
Subtract 378 from 400 to 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.

After the division, we end up with 10060.59523809 and a remainder of 2.2e-08.
