We look at the division of 89120107 by 615 
We want to divide 89120107 by 615.

Going ahead to step 1:
When dividing 8 by 615, we get 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.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 615

Moving on to step 2:
615 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 615

Advancing to step 3:
If we divide 891 by 615, we get 1 and a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 276 after subtracting 615 from 891.
Fetch the next digit (2) from the dividend, attach it to 276 and continue: 2762 / 615

On to step 4:
When dividing 2762 by 615, we get 4 with a remainder of 302.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 2460 from 2762 to get 302.
Append the next digit (0) from the dividend to 302 and continue with: 3020 / 615

Step 5:
615 goes into 3020 4 times with a remainder of 560.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 2460 from 3020 leaves us with 560.
Include the next digit (1) from the dividend after 560, then repeat: 5601 / 615

Step 6:
When dividing 5601 by 615, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 1449.0
The remainder is 66 after subtracting 5535 from 5601.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 615

Step 7:
615 can be fit into 660 1 times, resulting in a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 14491.0
Subtract 615 from 660 to get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 615

Going ahead to step 8:
615 can be fit into 457 0 times, resulting in a remainder of 457.
The next digit of our result is 0. 
Result so far: 144910.0
If we take 0 away from 457, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 9:
The number 615 fits into 4570 7 times, leaving a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 144910.7
Subtracting 4305 from 4570 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 10:
If we divide 2650 by 615, we get 4 and a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 144910.74
If we take 2460 away from 2650, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
1900 divided by 615 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 144910.743
Subtract 1845 from 1900 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.

Going ahead to step 12:
615 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 144910.743
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 13:
615 can be fit into 5500 8 times, resulting in a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 144910.74308
If we subtract 4920 from 5500, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 14:
615 can be fit into 5800 9 times, resulting in a remainder of 265.
Record the quotient 9 as the next digit in the result. 
Result so far: 144910.743089
Subtracting 5535 from 5800 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 15:
The number 615 fits into 2650 4 times, leaving a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 144910.7430894
The remainder is 190 after subtracting 2460 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 16:
615 can be fit into 1900 3 times, resulting in a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 144910.74308943
Deduct 1845 from 1900 and we're left with 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 144910.74308943, with a leftover of 5.5e-08.
