74840603 ÷ 129 
We want to divide 74840603 by 129.

Step 1:
129 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 129

Moving on to step 2:
129 goes into 74 0 times with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 129

On to step 3:
The number 129 fits into 748 5 times, leaving a remainder of 103.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 103 after subtracting 645 from 748.
Include the next digit (4) from the dividend after 103, then repeat: 1034 / 129

Step 4:
129 goes into 1034 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 1032 from 1034 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 129

Moving on to step 5:
The number 129 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 580.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 129

Going ahead to step 6:
When dividing 206 by 129, we get 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 5801.0
Deduct 129 from 206 and we're left with 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 129

Step 7:
129 goes into 770 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 58015.0
If we take 645 away from 770, we end up with 125.
Include the next digit (3) from the dividend after 125, then repeat: 1253 / 129

Let's proceed to step 8:
1253 divided by 129 is 9 with a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 580159.0
Subtracting 1161 from 1253 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.

Moving on to step 9:
129 can be fit into 920 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 580159.7
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 10:
If we divide 170 by 129, we get 1 and a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 580159.71
If we take 129 away from 170, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
The number 129 fits into 410 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 580159.713
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
The number 129 fits into 230 1 times, leaving a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 580159.7131
Subtracting 129 from 230 leaves us 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.

Moving on to step 13:
129 goes into 1010 7 times with a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 580159.71317
If we subtract 903 from 1010, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 14:
The number 129 fits into 1070 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 580159.713178
If we take 1032 away from 1070, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 15:
The number 129 fits into 380 2 times, leaving a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 580159.7131782
Subtracting 258 from 380 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 16:
129 goes into 1220 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 580159.71317829
Deduct 1161 from 1220 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 580159.71317829 with a remaining 5.9e-08.
