We look at the division of 105720 by 85 
Let's see how many times 85 fits into 105720.

On to step 1:
85 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 85

Advancing to step 2:
85 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 85

On to step 3:
If we divide 105 by 85, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 85 away from 105, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 85

Going ahead to step 4:
85 goes into 207 2 times with a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 170 from 207 and we're left with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 85

Moving on to step 5:
85 goes into 372 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 340 from 372 to get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 85

Going ahead to step 6:
When dividing 320 by 85, we get 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 1243.0
If we subtract 255 from 320, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
85 can be fit into 650 7 times, resulting in a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 1243.7
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
The number 85 fits into 550 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1243.76
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 85, we get 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 1243.764
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
85 goes into 600 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1243.7647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1243.7647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1243.764705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
When dividing 750 by 85, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 1243.7647058
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1243.76470588
If we take 680 away from 700, we end up 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 1243.76470588, with a leftover of 2e-08.
