We look at the division of 40201420 by 859 
Our goal is to divide 40201420 by 859.

Let's proceed to step 1:
The number 859 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 859

Let's proceed to step 2:
The number 859 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 859

On to step 3:
859 can be fit into 402 0 times, resulting in a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 402 leaves us with 402.
Bring next digit (0) of the dividend behind the 402 and repeat the process: 4020 / 859

On to step 4:
4020 divided by 859 is 4 with a remainder of 584.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3436 from 4020 leaves us with 584.
Append the next digit (1) from the dividend to 584 and continue with: 5841 / 859

Let's proceed to step 5:
859 goes into 5841 6 times with a remainder of 687.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 5154 from 5841, we get 687.
Include the next digit (4) from the dividend after 687, then repeat: 6874 / 859

Moving on to step 6:
859 goes into 6874 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 468.0
If we subtract 6872 from 6874, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 859

Advancing to step 7:
If we divide 22 by 859, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 4680.0
Subtracting 0 from 22 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 859

Going ahead to step 8:
The number 859 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 46800.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 9:
The number 859 fits into 2200 2 times, leaving a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 46800.2
Deduct 1718 from 2200 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 10:
If we divide 4820 by 859, we get 5 and a remainder of 525.
Write down 5 as next digit of the result. 
Result so far: 46800.25
If we subtract 4295 from 4820, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 11:
859 goes into 5250 6 times with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 46800.256
Deduct 5154 from 5250 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
859 can be fit into 960 1 times, resulting in a remainder of 101.
The next digit of our result is 1. 
Result so far: 46800.2561
If we subtract 859 from 960, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 13:
1010 divided by 859 is 1 with a remainder of 151.
Record the quotient 1 as the next digit in the result. 
Result so far: 46800.25611
If we subtract 859 from 1010, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 46800.25611, with a leftover of 0.000151.
