We look at the division of 79999545 by 870 
We're looking to find how many times 870 goes into 79999545.

Let's proceed to step 1:
870 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 870

Step 2:
870 can be fit into 79 0 times, resulting in a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 870

Step 3:
The number 870 fits into 799 0 times, leaving a remainder of 799.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 799 leaves us with 799.
Include the next digit (9) from the dividend after 799, then repeat: 7999 / 870

Step 4:
7999 divided by 870 is 9 with a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7830 from 7999 leaves us with 169.
Append the next digit (9) from the dividend to 169 and continue with: 1699 / 870

On to step 5:
1699 divided by 870 is 1 with a remainder of 829.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 829 after subtracting 870 from 1699.
Append the next digit (5) from the dividend to 829 and continue with: 8295 / 870

Moving on to step 6:
If we divide 8295 by 870, we get 9 and a remainder of 465.
Use 9 as the next digit of our solution. 
Result so far: 919.0
The remainder is 465 after subtracting 7830 from 8295.
Fetch the next digit (4) from the dividend, attach it to 465 and continue: 4654 / 870

On to step 7:
4654 divided by 870 is 5 with a remainder of 304.
Put 5 as the next digit of the answer. 
Result so far: 9195.0
If we subtract 4350 from 4654, we get 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 870

Going ahead to step 8:
The number 870 fits into 3045 3 times, leaving a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 91953.0
If we take 2610 away from 3045, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 9:
If we divide 4350 by 870, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 91953.5
Subtracting 4350 from 4350 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.

Going ahead to step 10:
When dividing 0 by 870, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 91953.5
Deduct 0 from 0 and we're left 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.

Step 11:
0 divided by 870 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 91953.5
If we subtract 0 from 0, we get 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 91953.5 and a remainder of 0.0.
