We're dividing 72901636 by 129 
We want to figure out the number of times 72901636 can be divided by 129.

Advancing to step 1:
If we divide 7 by 129, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 129

Moving on to step 2:
If we divide 72 by 129, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 129

Let's proceed to step 3:
The number 129 fits into 729 5 times, leaving a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 645 from 729 and we're left with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 129

On to step 4:
840 divided by 129 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 774 from 840 and we're left with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 129

Let's proceed to step 5:
When dividing 661 by 129, we get 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 565.0
If we subtract 645 from 661, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 129

Let's proceed to step 6:
The number 129 fits into 166 1 times, leaving a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 5651.0
Subtract 129 from 166 to get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 129

Moving on to step 7:
The number 129 fits into 373 2 times, leaving a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 56512.0
If we subtract 258 from 373, we get 115.
Include the next digit (6) from the dividend after 115, then repeat: 1156 / 129

Going ahead to step 8:
129 can be fit into 1156 8 times, resulting in a remainder of 124.
Use 8 as the next digit of our solution. 
Result so far: 565128.0
If we subtract 1032 from 1156, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
1240 divided by 129 is 9 with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 565128.9
Subtract 1161 from 1240 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
790 divided by 129 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 565128.96
Subtract 774 from 790 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 129, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 565128.961
Subtracting 129 from 160 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
129 can be fit into 310 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 565128.9612
The remainder is 52 after subtracting 258 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
When dividing 520 by 129, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 565128.96124
If we take 516 away from 520, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 129 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 565128.96124
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
When dividing 400 by 129, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 565128.9612403
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 16:
129 can be fit into 130 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 565128.96124031
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 565128.96124031 with a balance of 1e-09.
