Let's divide 40475157 by 421
We want to figure out the number of times 40475157 can be divided by 421.

Moving on to step 1:
The number 421 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 421

Let's proceed to step 2:
When dividing 40 by 421, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 421

Let's proceed to step 3:
421 goes into 404 0 times with a remainder of 404.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 404 after subtracting 0 from 404.
Grab the next digit (7) from the dividend, add it to 404, then carry on: 4047 / 421

Advancing to step 4:
The number 421 fits into 4047 9 times, leaving a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 258 after subtracting 3789 from 4047.
Grab the next digit (5) from the dividend, add it to 258, then carry on: 2585 / 421

Moving on to step 5:
421 goes into 2585 6 times with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 2526 from 2585 to get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 421

Moving on to step 6:
421 can be fit into 591 1 times, resulting in a remainder of 170.
The next digit of our result is 1. 
Result so far: 961.0
If we subtract 421 from 591, we get 170.
Fetch the next digit (5) from the dividend, attach it to 170 and continue: 1705 / 421

Step 7:
421 goes into 1705 4 times with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 9614.0
Subtracting 1684 from 1705 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 421

Going ahead to step 8:
217 divided by 421 is 0 with a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 96140.0
Subtract 0 from 217 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 9:
If we divide 2170 by 421, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 96140.5
Deduct 2105 from 2170 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
When dividing 650 by 421, we get 1 with a remainder of 229.
The next digit of our result is 1. 
Result so far: 96140.51
Subtract 421 from 650 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 11:
421 goes into 2290 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 96140.515
Deduct 2105 from 2290 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 12:
421 goes into 1850 4 times with a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 96140.5154
Subtracting 1684 from 1850 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 13:
421 can be fit into 1660 3 times, resulting in a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 96140.51543
If we take 1263 away from 1660, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 14:
When dividing 3970 by 421, we get 9 with a remainder of 181.
Put 9 as the next digit of the answer. 
Result so far: 96140.515439
If we subtract 3789 from 3970, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 15:
The number 421 fits into 1810 4 times, leaving a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 96140.5154394
The remainder is 126 after subtracting 1684 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 16:
When dividing 1260 by 421, we get 2 with a remainder of 418.
Record the quotient 2 as the next digit in the result. 
Result so far: 96140.51543942
The remainder is 418 after subtracting 842 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 96140.51543942, with a leftover of 4.18e-07.
