Let's divide 70923552 by 644
We want to divide 70923552 by 644.

On to step 1:
The number 644 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 644

Step 2:
644 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 644

Moving on to step 3:
When dividing 709 by 644, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 644 from 709, we get 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 644

Going ahead to step 4:
When dividing 652 by 644, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 8 after subtracting 644 from 652.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 644

Advancing to step 5:
When dividing 83 by 644, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 644

Moving on to step 6:
If we divide 835 by 644, we get 1 and a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
Deduct 644 from 835 and we're left with 191.
Include the next digit (5) from the dividend after 191, then repeat: 1915 / 644

Moving on to step 7:
The number 644 fits into 1915 2 times, leaving a remainder of 627.
Put 2 as the next digit of the answer. 
Result so far: 11012.0
Deduct 1288 from 1915 and we're left with 627.
Bring next digit (2) of the dividend behind the 627 and repeat the process: 6272 / 644

Going ahead to step 8:
If we divide 6272 by 644, we get 9 and a remainder of 476.
Put 9 as the next digit of the answer. 
Result so far: 110129.0
The remainder is 476 after subtracting 5796 from 6272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 9:
644 goes into 4760 7 times with a remainder of 252.
The next digit of our result is 7. 
Result so far: 110129.7
Subtracting 4508 from 4760 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
The number 644 fits into 2520 3 times, leaving a remainder of 588.
Put 3 as the next digit of the answer. 
Result so far: 110129.73
Deduct 1932 from 2520 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 11:
5880 divided by 644 is 9 with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 110129.739
The remainder is 84 after subtracting 5796 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
644 can be fit into 840 1 times, resulting in a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 110129.7391
Subtract 644 from 840 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 13:
When dividing 1960 by 644, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 110129.73913
Subtracting 1932 from 1960 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
The number 644 fits into 280 0 times, leaving a remainder of 280.
The next digit of our result is 0. 
Result so far: 110129.73913
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
2800 divided by 644 is 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 110129.7391304
The remainder is 224 after subtracting 2576 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 16:
644 goes into 2240 3 times with a remainder of 308.
The next digit of our result is 3. 
Result so far: 110129.73913043
Deduct 1932 from 2240 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final outcome is 110129.73913043, with a leftover of 3.08e-07.
