We look at the division of 42270644 by 524 
We want to divide 42270644 by 524.

Moving on to step 1:
524 goes into 4 0 times with 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 524

Let's proceed to step 2:
When dividing 42 by 524, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 524

Let's proceed to step 3:
If we divide 422 by 524, we get 0 and a remainder of 422.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 422 and we're left with 422.
Take the next digit (7) from the dividend and append it to 422, then repeat: 4227 / 524

Step 4:
If we divide 4227 by 524, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 35 after subtracting 4192 from 4227.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 524

Going ahead to step 5:
524 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 350 and we're left with 350.
Grab the next digit (6) from the dividend, add it to 350, then carry on: 3506 / 524

Going ahead to step 6:
When dividing 3506 by 524, we get 6 with a remainder of 362.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
Deduct 3144 from 3506 and we're left with 362.
Fetch the next digit (4) from the dividend, attach it to 362 and continue: 3624 / 524

Going ahead to step 7:
524 goes into 3624 6 times with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 8066.0
Subtract 3144 from 3624 to get 480.
Append the next digit (4) from the dividend to 480 and continue with: 4804 / 524

Advancing to step 8:
524 can be fit into 4804 9 times, resulting in a remainder of 88.
The next digit of our result is 9. 
Result so far: 80669.0
The remainder is 88 after subtracting 4716 from 4804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
524 goes into 880 1 times with a remainder of 356.
Use 1 as the next digit of our solution. 
Result so far: 80669.1
Subtracting 524 from 880 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 10:
If we divide 3560 by 524, we get 6 and a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 80669.16
The remainder is 416 after subtracting 3144 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 11:
4160 divided by 524 is 7 with a remainder of 492.
Write down 7 as next digit of the result. 
Result so far: 80669.167
The remainder is 492 after subtracting 3668 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 12:
524 goes into 4920 9 times with a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 80669.1679
If we subtract 4716 from 4920, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 13:
The number 524 fits into 2040 3 times, leaving a remainder of 468.
The number 3 becomes the next digit in our result. 
Result so far: 80669.16793
Deduct 1572 from 2040 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 14:
524 can be fit into 4680 8 times, resulting in a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 80669.167938
The remainder is 488 after subtracting 4192 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 15:
524 goes into 4880 9 times with a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 80669.1679389
If we subtract 4716 from 4880, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 16:
1640 divided by 524 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 80669.16793893
If we take 1572 away from 1640, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 80669.16793893 with a remaining 6.8e-08.
