We look at the division of 36912717 by 129 
We want to figure out the number of times 36912717 can be divided by 129.

Advancing to step 1:
129 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 129

Let's proceed to step 2:
129 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 129

Going ahead to step 3:
369 divided by 129 is 2 with a remainder of 111.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 258 from 369 to get 111.
Grab the next digit (1) from the dividend, add it to 111, then carry on: 1111 / 129

Moving on to step 4:
If we divide 1111 by 129, we get 8 and a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 1032 away from 1111, we end up with 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 129

Advancing to step 5:
The number 129 fits into 792 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
The remainder is 18 after subtracting 774 from 792.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 129

Going ahead to step 6:
187 divided by 129 is 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 2861.0
If we subtract 129 from 187, we get 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 129

Advancing to step 7:
129 goes into 581 4 times with a remainder of 65.
The next digit of our result is 4. 
Result so far: 28614.0
If we subtract 516 from 581, we get 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 129

Let's proceed to step 8:
129 goes into 657 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 286145.0
Deduct 645 from 657 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
129 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 286145.0
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
The number 129 fits into 1200 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 286145.09
Subtract 1161 from 1200 to 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.

Let's proceed to step 11:
When dividing 390 by 129, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 286145.093
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
129 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 286145.093
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
129 goes into 300 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 286145.09302
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
129 goes into 420 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 286145.093023
Deduct 387 from 420 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 15:
330 divided by 129 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 286145.0930232
The remainder is 72 after subtracting 258 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
When dividing 720 by 129, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 286145.09302325
If we subtract 645 from 720, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 286145.09302325, with a leftover of 7.5e-08.
