79017316 divided by 870 
We're looking to find how many times 870 goes into 79017316.

Advancing to step 1:
The number 870 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 870

Let's proceed to step 2:
79 divided by 870 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 870

Advancing to step 3:
The number 870 fits into 790 0 times, leaving a remainder of 790.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 790 and we're left with 790.
Include the next digit (1) from the dividend after 790, then repeat: 7901 / 870

Going ahead to step 4:
870 can be fit into 7901 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7830 from 7901 to get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 870

Going ahead to step 5:
870 goes into 717 0 times with a remainder of 717.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 717, we end up with 717.
Grab the next digit (3) from the dividend, add it to 717, then carry on: 7173 / 870

Moving on to step 6:
870 goes into 7173 8 times with a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 908.0
Deduct 6960 from 7173 and we're left with 213.
Grab the next digit (1) from the dividend, add it to 213, then carry on: 2131 / 870

On to step 7:
2131 divided by 870 is 2 with a remainder of 391.
Record the quotient 2 as the next digit in the result. 
Result so far: 9082.0
If we subtract 1740 from 2131, we get 391.
Append the next digit (6) from the dividend to 391 and continue with: 3916 / 870

Let's proceed to step 8:
When dividing 3916 by 870, we get 4 with a remainder of 436.
Use 4 as the next digit of our solution. 
Result so far: 90824.0
If we subtract 3480 from 3916, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 9:
The number 870 fits into 4360 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 90824.5
Subtracting 4350 from 4360 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
870 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 90824.5
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
870 can be fit into 1000 1 times, resulting in a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 90824.501
If we take 870 away from 1000, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
870 goes into 1300 1 times with a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 90824.5011
Subtracting 870 from 1300 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 90824.5011 with a balance of 0.0043.
