We look at the division of 861035 by 20 
We want to figure out the number of times 861035 can be divided by 20.

Moving on to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

Going ahead to step 2:
If we divide 86 by 20, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 80 from 86 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 20

Advancing to step 3:
61 divided by 20 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 1 after subtracting 60 from 61.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

On to step 4:
When dividing 10 by 20, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 430.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 20

Advancing to step 5:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 4305.0
The remainder is 3 after subtracting 100 from 103.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Going ahead to step 6:
If we divide 35 by 20, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 43051.0
If we subtract 20 from 35, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 43051.7
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 43051.75
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43051.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 43051.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 43051.75 and a remainder of 0.0.
