Let's divide 87864957 by 79
Our goal is to divide 87864957 by 79.

Let's proceed to step 1:
8 divided by 79 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 79

Going ahead to step 2:
79 can be fit into 87 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 79 from 87 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 79

Moving on to step 3:
The number 79 fits into 88 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 79 from 88 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 79

Going ahead to step 4:
96 divided by 79 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we subtract 79 from 96, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 79

Step 5:
79 goes into 174 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1112.0
If we subtract 158 from 174, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 79

Step 6:
79 goes into 169 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 11122.0
If we subtract 158 from 169, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 79

Going ahead to step 7:
79 can be fit into 115 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 111221.0
The remainder is 36 after subtracting 79 from 115.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 79

Step 8:
If we divide 367 by 79, we get 4 and a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 1112214.0
Subtracting 316 from 367 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.

Let's proceed to step 9:
79 goes into 510 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1112214.6
Subtracting 474 from 510 leaves us 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.

Going ahead to step 10:
The number 79 fits into 360 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 1112214.64
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 11:
79 can be fit into 440 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1112214.645
Subtracting 395 from 440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
If we divide 450 by 79, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 1112214.6455
Subtract 395 from 450 to 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 1112214.6455, with a leftover of 0.00055.
