We're dividing 81420433 by 629 
Our goal is to divide 81420433 by 629.

Let's proceed to step 1:
8 divided by 629 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 629

Let's proceed to step 2:
When dividing 81 by 629, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 629

On to step 3:
The number 629 fits into 814 1 times, leaving a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 629 from 814, we get 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 629

On to step 4:
629 goes into 1852 2 times with a remainder of 594.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1258 away from 1852, we end up with 594.
Append the next digit (0) from the dividend to 594 and continue with: 5940 / 629

Step 5:
5940 divided by 629 is 9 with a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Deduct 5661 from 5940 and we're left with 279.
Grab the next digit (4) from the dividend, add it to 279, then carry on: 2794 / 629

Advancing to step 6:
The number 629 fits into 2794 4 times, leaving a remainder of 278.
The next digit of our result is 4. 
Result so far: 1294.0
Subtracting 2516 from 2794 leaves us with 278.
Bring next digit (3) of the dividend behind the 278 and repeat the process: 2783 / 629

Going ahead to step 7:
2783 divided by 629 is 4 with a remainder of 267.
The number 4 becomes the next digit in our result. 
Result so far: 12944.0
Subtracting 2516 from 2783 leaves us with 267.
Bring next digit (3) of the dividend behind the 267 and repeat the process: 2673 / 629

Let's proceed to step 8:
If we divide 2673 by 629, we get 4 and a remainder of 157.
The number 4 becomes the next digit in our result. 
Result so far: 129444.0
The remainder is 157 after subtracting 2516 from 2673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
When dividing 1570 by 629, we get 2 with a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 129444.2
Subtracting 1258 from 1570 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 10:
If we divide 3120 by 629, we get 4 and a remainder of 604.
Use 4 as the next digit of our solution. 
Result so far: 129444.24
Subtracting 2516 from 3120 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 11:
629 can be fit into 6040 9 times, resulting in a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 129444.249
The remainder is 379 after subtracting 5661 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 12:
629 can be fit into 3790 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 129444.2496
If we subtract 3774 from 3790, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 629, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 129444.2496
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
629 can be fit into 1600 2 times, resulting in a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 129444.249602
Deduct 1258 from 1600 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 15:
The number 629 fits into 3420 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 129444.2496025
If we subtract 3145 from 3420, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 16:
629 goes into 2750 4 times with a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 129444.24960254
Deduct 2516 from 2750 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final result is 129444.24960254 with a remainder of 2.34e-07.
