Let's divide 70385621 by 829
We want to divide 70385621 by 829.

Going ahead to step 1:
7 divided by 829 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 829

Step 2:
829 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 829

On to step 3:
829 can be fit into 703 0 times, resulting in a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 703, we end up with 703.
Bring next digit (8) of the dividend behind the 703 and repeat the process: 7038 / 829

Moving on to step 4:
The number 829 fits into 7038 8 times, leaving a remainder of 406.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6632 from 7038, we get 406.
Grab the next digit (5) from the dividend, add it to 406, then carry on: 4065 / 829

On to step 5:
If we divide 4065 by 829, we get 4 and a remainder of 749.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 3316 from 4065, we get 749.
Append the next digit (6) from the dividend to 749 and continue with: 7496 / 829

Advancing to step 6:
When dividing 7496 by 829, we get 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
If we subtract 7461 from 7496, we get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 829

Moving on to step 7:
829 goes into 352 0 times with a remainder of 352.
Put 0 as the next digit of the answer. 
Result so far: 8490.0
Subtracting 0 from 352 leaves us with 352.
Append the next digit (1) from the dividend to 352 and continue with: 3521 / 829

Going ahead to step 8:
829 can be fit into 3521 4 times, resulting in a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 84904.0
The remainder is 205 after subtracting 3316 from 3521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 9:
The number 829 fits into 2050 2 times, leaving a remainder of 392.
The next digit of our result is 2. 
Result so far: 84904.2
Subtracting 1658 from 2050 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 10:
3920 divided by 829 is 4 with a remainder of 604.
The next digit of our result is 4. 
Result so far: 84904.24
The remainder is 604 after subtracting 3316 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 11:
829 goes into 6040 7 times with a remainder of 237.
The next digit of our result is 7. 
Result so far: 84904.247
Subtract 5803 from 6040 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Moving on to step 12:
When dividing 2370 by 829, we get 2 with a remainder of 712.
The number 2 becomes the next digit in our result. 
Result so far: 84904.2472
Subtract 1658 from 2370 to get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 13:
If we divide 7120 by 829, we get 8 and a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 84904.24728
The remainder is 488 after subtracting 6632 from 7120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 14:
829 can be fit into 4880 5 times, resulting in a remainder of 735.
The number 5 becomes the next digit in our result. 
Result so far: 84904.247285
The remainder is 735 after subtracting 4145 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 15:
The number 829 fits into 7350 8 times, leaving a remainder of 718.
The number 8 becomes the next digit in our result. 
Result so far: 84904.2472858
Subtract 6632 from 7350 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Going ahead to step 16:
The number 829 fits into 7180 8 times, leaving a remainder of 548.
The next digit of our result is 8. 
Result so far: 84904.24728588
The remainder is 548 after subtracting 6632 from 7180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final outcome is 84904.24728588, with a leftover of 5.48e-07.
