We divide 529191 by 40
Our goal is to divide 529191 by 40.

On to step 1:
40 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 40

Going ahead to step 2:
40 goes into 52 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 40 away from 52, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 40

Let's proceed to step 3:
If we divide 129 by 40, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 120 from 129, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 40

Going ahead to step 4:
40 goes into 91 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 132.0
The remainder is 11 after subtracting 80 from 91.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 40

Let's proceed to step 5:
40 goes into 119 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 1322.0
Subtract 80 from 119 to get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 40

Let's proceed to step 6:
If we divide 391 by 40, we get 9 and a remainder of 31.
The next digit of our result is 9. 
Result so far: 13229.0
Deduct 360 from 391 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
When dividing 310 by 40, we get 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 13229.7
If we subtract 280 from 310, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 13229.77
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 13229.77, with a leftover of 0.02.
