We look at the division of 79489178 by 109 
We want to divide 79489178 by 109.

Let's proceed to step 1:
If we divide 7 by 109, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 109

Let's proceed to step 2:
109 can be fit into 79 0 times, resulting in a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 109

On to step 3:
109 can be fit into 794 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 763 from 794 to get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 109

Moving on to step 4:
109 can be fit into 318 2 times, resulting in a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 100 after subtracting 218 from 318.
Fetch the next digit (9) from the dividend, attach it to 100 and continue: 1009 / 109

Let's proceed to step 5:
If we divide 1009 by 109, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 729.0
Subtract 981 from 1009 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 109

On to step 6:
281 divided by 109 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 7292.0
Deduct 218 from 281 and we're left with 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 109

Moving on to step 7:
If we divide 637 by 109, we get 5 and a remainder of 92.
Use 5 as the next digit of our solution. 
Result so far: 72925.0
If we take 545 away from 637, we end up with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 109

Moving on to step 8:
109 goes into 928 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 729258.0
Subtract 872 from 928 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
109 goes into 560 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 729258.5
The remainder is 15 after subtracting 545 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 109 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 729258.51
Subtracting 109 from 150 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
The number 109 fits into 410 3 times, leaving a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 729258.513
Deduct 327 from 410 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 12:
If we divide 830 by 109, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 729258.5137
Subtract 763 from 830 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
When dividing 670 by 109, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 729258.51376
Deduct 654 from 670 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 109 is 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 729258.513761
If we take 109 away from 160, we end up 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.

Advancing to step 15:
109 goes into 510 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 729258.5137614
Subtract 436 from 510 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 16:
The number 109 fits into 740 6 times, leaving a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 729258.51376146
The remainder is 86 after subtracting 654 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 729258.51376146 with a remainder of 8.6e-08.
