52376720 divided by 129 
We want to figure out the number of times 52376720 can be divided by 129.

Step 1:
The number 129 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 129

On to step 2:
If we divide 52 by 129, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 129

Going ahead to step 3:
The number 129 fits into 523 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 7 after subtracting 516 from 523.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 129

Going ahead to step 4:
129 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 77, we get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 129

Advancing to step 5:
When dividing 776 by 129, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 406.0
Subtract 774 from 776 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 129

Going ahead to step 6:
When dividing 27 by 129, we get 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 4060.0
If we take 0 away from 27, we end up with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 129

Moving on to step 7:
129 goes into 272 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 40602.0
If we subtract 258 from 272, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 129

Step 8:
129 can be fit into 140 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 406021.0
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
129 can be fit into 110 0 times, resulting in a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 406021.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
1100 divided by 129 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 406021.08
Subtract 1032 from 1100 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
129 goes into 680 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 406021.085
Deduct 645 from 680 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
129 can be fit into 350 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 406021.0852
Subtracting 258 from 350 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
The number 129 fits into 920 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 406021.08527
The remainder is 17 after subtracting 903 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
170 divided by 129 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 406021.085271
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 15:
129 goes into 410 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 406021.0852713
Subtract 387 from 410 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 16:
230 divided by 129 is 1 with a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 406021.08527131
If we take 129 away from 230, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

After the division, we end up with 406021.08527131 and a remainder of 1.01e-07.
