We look at the division of 644046 by 88 
We want to divide 644046 by 88.

Going ahead to step 1:
6 divided by 88 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 88

Step 2:
The number 88 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 88

Advancing to step 3:
When dividing 644 by 88, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 28 after subtracting 616 from 644.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 88

Advancing to step 4:
If we divide 280 by 88, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 16 after subtracting 264 from 280.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 88

Step 5:
88 can be fit into 164 1 times, resulting in a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 731.0
Subtracting 88 from 164 leaves us with 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 88

Let's proceed to step 6:
If we divide 766 by 88, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 7318.0
Deduct 704 from 766 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
88 goes into 620 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7318.7
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 88, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7318.7
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
When dividing 400 by 88, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 7318.704
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 88, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 7318.7045
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 88 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 7318.70454
If we take 352 away from 400, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
88 goes into 480 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 7318.704545
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
88 can be fit into 400 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7318.7045454
If we take 352 away from 400, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
88 can be fit into 480 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 7318.70454545
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 7318.70454545, with a leftover of 4e-08.
