We look at the division of 57649447 by 129 
We want to figure out the number of times 57649447 can be divided by 129.

On to step 1:
When dividing 5 by 129, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 129

Going ahead to step 2:
129 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (6) from the dividend and append it to 57, then repeat: 576 / 129

Let's proceed to step 3:
If we divide 576 by 129, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 516 from 576 leaves us with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 129

Step 4:
The number 129 fits into 604 4 times, leaving a remainder of 88.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 516 from 604 leaves us with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 129

Moving on to step 5:
When dividing 889 by 129, we get 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
Deduct 774 from 889 and we're left with 115.
Include the next digit (4) from the dividend after 115, then repeat: 1154 / 129

Let's proceed to step 6:
129 can be fit into 1154 8 times, resulting in a remainder of 122.
The next digit of our result is 8. 
Result so far: 4468.0
Subtract 1032 from 1154 to get 122.
Grab the next digit (4) from the dividend, add it to 122, then carry on: 1224 / 129

Advancing to step 7:
1224 divided by 129 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 44689.0
The remainder is 63 after subtracting 1161 from 1224.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 129

Step 8:
129 goes into 637 4 times with a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 446894.0
The remainder is 121 after subtracting 516 from 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
129 goes into 1210 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 446894.9
Subtracting 1161 from 1210 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
If we divide 490 by 129, we get 3 and a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 446894.93
Subtracting 387 from 490 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
1030 divided by 129 is 7 with a remainder of 127.
Write down 7 as next digit of the result. 
Result so far: 446894.937
Subtracting 903 from 1030 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
If we divide 1270 by 129, we get 9 and a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 446894.9379
The remainder is 109 after subtracting 1161 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 13:
When dividing 1090 by 129, we get 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 446894.93798
Deduct 1032 from 1090 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
580 divided by 129 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 446894.937984
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
129 can be fit into 640 4 times, resulting in a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 446894.9379844
The remainder is 124 after subtracting 516 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 446894.9379844 with a remainder of 1.24e-06.
