We're dividing 857170 by 79 
We want to figure out the number of times 857170 can be divided by 79.

Step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 79

Going ahead to step 2:
79 can be fit into 85 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 79 from 85 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 79

On to step 3:
79 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 67 leaves us with 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 79

Step 4:
671 divided by 79 is 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 632 from 671, we get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 79

Moving on to step 5:
79 can be fit into 397 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1085.0
Subtracting 395 from 397 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 79

Going ahead to step 6:
79 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10850.0
Subtracting 0 from 20 leaves us 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.

Step 7:
The number 79 fits into 200 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 10850.2
If we take 158 away from 200, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
79 can be fit into 420 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 10850.25
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 10850.253
Subtracting 237 from 250 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 79 fits into 130 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 10850.2531
Subtracting 79 from 130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 11:
The number 79 fits into 510 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 10850.25316
If we take 474 away from 510, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
79 can be fit into 360 4 times, resulting in a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 10850.253164
If we take 316 away from 360, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
440 divided by 79 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10850.2531645
If we subtract 395 from 440, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
If we divide 450 by 79, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 10850.25316455
If we subtract 395 from 450, 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.

The final outcome is 10850.25316455, with a leftover of 5.5e-08.
