Let's divide 71442745 by 129
We want to figure out the number of times 71442745 can be divided by 129.

Let's proceed to step 1:
The number 129 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 129

Advancing to step 2:
129 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 129

Let's proceed to step 3:
129 can be fit into 714 5 times, resulting in a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 645 away from 714, we end up with 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 129

Step 4:
694 divided by 129 is 5 with a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 645 from 694 and we're left with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 129

On to step 5:
When dividing 492 by 129, we get 3 with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 553.0
Deduct 387 from 492 and we're left with 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 129

On to step 6:
When dividing 1057 by 129, we get 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 5538.0
If we take 1032 away from 1057, we end up with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 129

Step 7:
129 can be fit into 254 1 times, resulting in a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 55381.0
Deduct 129 from 254 and we're left with 125.
Grab the next digit (5) from the dividend, add it to 125, then carry on: 1255 / 129

Let's proceed to step 8:
If we divide 1255 by 129, we get 9 and a remainder of 94.
The next digit of our result is 9. 
Result so far: 553819.0
Deduct 1161 from 1255 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
If we divide 940 by 129, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 553819.7
If we subtract 903 from 940, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
129 can be fit into 370 2 times, resulting in a remainder of 112.
The next digit of our result is 2. 
Result so far: 553819.72
Deduct 258 from 370 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
129 can be fit into 1120 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 553819.728
The remainder is 88 after subtracting 1032 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
129 goes into 880 6 times with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 553819.7286
If we take 774 away from 880, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 13:
If we divide 1060 by 129, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 553819.72868
If we subtract 1032 from 1060, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
If we divide 280 by 129, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 553819.728682
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 15:
The number 129 fits into 220 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 553819.7286821
Deduct 129 from 220 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 16:
910 divided by 129 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 553819.72868217
If we subtract 903 from 910, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 553819.72868217, with a leftover of 7e-09.
