We're dividing 13587606 by 109 
We want to figure out the number of times 13587606 can be divided by 109.

Step 1:
109 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 109

Moving on to step 2:
109 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 109

Advancing to step 3:
109 goes into 135 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 109 from 135 to get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 109

On to step 4:
109 goes into 268 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 50 after subtracting 218 from 268.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 109

Advancing to step 5:
109 can be fit into 507 4 times, resulting in a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 436 from 507 leaves us with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 109

Step 6:
The number 109 fits into 716 6 times, leaving a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 1246.0
Subtract 654 from 716 to get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 109

Step 7:
When dividing 620 by 109, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 12465.0
Subtract 545 from 620 to get 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 109

On to step 8:
The number 109 fits into 756 6 times, leaving a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 124656.0
The remainder is 102 after subtracting 654 from 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
109 goes into 1020 9 times with a remainder of 39.
The next digit of our result is 9. 
Result so far: 124656.9
If we subtract 981 from 1020, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
390 divided by 109 is 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 124656.93
The remainder is 63 after subtracting 327 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
When dividing 630 by 109, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 124656.935
Subtracting 545 from 630 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
109 goes into 850 7 times with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 124656.9357
If we subtract 763 from 850, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
If we divide 870 by 109, we get 7 and a remainder of 107.
The next digit of our result is 7. 
Result so far: 124656.93577
If we subtract 763 from 870, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 124656.93577 and a remainder of 0.000107.
