70643129 ÷ 922 
Our goal is to divide 70643129 by 922.

On to step 1:
If we divide 7 by 922, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 922

Step 2:
The number 922 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 922

On to step 3:
If we divide 706 by 922, we get 0 and a remainder of 706.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 706 to get 706.
Include the next digit (4) from the dividend after 706, then repeat: 7064 / 922

Going ahead to step 4:
922 can be fit into 7064 7 times, resulting in a remainder of 610.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6454 from 7064 to get 610.
Bring next digit (3) of the dividend behind the 610 and repeat the process: 6103 / 922

On to step 5:
When dividing 6103 by 922, we get 6 with a remainder of 571.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 5532 from 6103 and we're left with 571.
Grab the next digit (1) from the dividend, add it to 571, then carry on: 5711 / 922

On to step 6:
5711 divided by 922 is 6 with a remainder of 179.
Use 6 as the next digit of our solution. 
Result so far: 766.0
Subtracting 5532 from 5711 leaves us with 179.
Append the next digit (2) from the dividend to 179 and continue with: 1792 / 922

Let's proceed to step 7:
1792 divided by 922 is 1 with a remainder of 870.
Record the quotient 1 as the next digit in the result. 
Result so far: 7661.0
If we subtract 922 from 1792, we get 870.
Fetch the next digit (9) from the dividend, attach it to 870 and continue: 8709 / 922

Going ahead to step 8:
The number 922 fits into 8709 9 times, leaving a remainder of 411.
The next digit of our result is 9. 
Result so far: 76619.0
Subtracting 8298 from 8709 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Moving on to step 9:
When dividing 4110 by 922, we get 4 with a remainder of 422.
The next digit of our result is 4. 
Result so far: 76619.4
If we take 3688 away from 4110, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 10:
The number 922 fits into 4220 4 times, leaving a remainder of 532.
Use 4 as the next digit of our solution. 
Result so far: 76619.44
Subtracting 3688 from 4220 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

The final result is 76619.44 with a remainder of 0.532.
