74904307 ÷ 129 
We're looking to find how many times 129 goes into 74904307.

Advancing to step 1:
129 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 129

Advancing to step 2:
74 divided by 129 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 129

Advancing to step 3:
129 can be fit into 749 5 times, resulting in a remainder of 104.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 645 away from 749, we end up with 104.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 129

Moving on to step 4:
The number 129 fits into 1040 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 1032 from 1040 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 129

On to step 5:
If we divide 84 by 129, we get 0 and a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 580.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 129

Step 6:
When dividing 843 by 129, we get 6 with a remainder of 69.
The next digit of our result is 6. 
Result so far: 5806.0
The remainder is 69 after subtracting 774 from 843.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 129

Step 7:
The number 129 fits into 690 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 58065.0
Deduct 645 from 690 and we're left with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 129

Going ahead to step 8:
129 goes into 457 3 times with a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 580653.0
Deduct 387 from 457 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
129 goes into 700 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 580653.5
Deduct 645 from 700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
129 can be fit into 550 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 580653.54
The remainder is 34 after subtracting 516 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
129 goes into 340 2 times with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 580653.542
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
129 can be fit into 820 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 580653.5426
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
129 can be fit into 460 3 times, resulting in a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 580653.54263
If we take 387 away from 460, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
730 divided by 129 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 580653.542635
Subtract 645 from 730 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 15:
The number 129 fits into 850 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 580653.5426356
Deduct 774 from 850 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
760 divided by 129 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 580653.54263565
If we take 645 away from 760, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final result is 580653.54263565 with a remainder of 1.15e-07.
