We divide 88643831 by 648
We want to figure out the number of times 88643831 can be divided by 648.

Let's proceed to step 1:
If we divide 8 by 648, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 648

Moving on to step 2:
When dividing 88 by 648, we get 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 648

Moving on to step 3:
648 can be fit into 886 1 times, resulting in a remainder of 238.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 648 from 886 to get 238.
Append the next digit (4) from the dividend to 238 and continue with: 2384 / 648

On to step 4:
648 can be fit into 2384 3 times, resulting in a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1944 away from 2384, we end up with 440.
Include the next digit (3) from the dividend after 440, then repeat: 4403 / 648

Moving on to step 5:
4403 divided by 648 is 6 with a remainder of 515.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we take 3888 away from 4403, we end up with 515.
Grab the next digit (8) from the dividend, add it to 515, then carry on: 5158 / 648

Step 6:
648 goes into 5158 7 times with a remainder of 622.
Record the quotient 7 as the next digit in the result. 
Result so far: 1367.0
If we take 4536 away from 5158, we end up with 622.
Grab the next digit (3) from the dividend, add it to 622, then carry on: 6223 / 648

Let's proceed to step 7:
If we divide 6223 by 648, we get 9 and a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 13679.0
Deduct 5832 from 6223 and we're left with 391.
Include the next digit (1) from the dividend after 391, then repeat: 3911 / 648

Let's proceed to step 8:
When dividing 3911 by 648, we get 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 136796.0
Deduct 3888 from 3911 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
If we divide 230 by 648, we get 0 and a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 136796.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
The number 648 fits into 2300 3 times, leaving a remainder of 356.
The next digit of our result is 3. 
Result so far: 136796.03
Subtracting 1944 from 2300 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
If we divide 3560 by 648, we get 5 and a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 136796.035
Deduct 3240 from 3560 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
When dividing 3200 by 648, we get 4 with a remainder of 608.
The next digit of our result is 4. 
Result so far: 136796.0354
Deduct 2592 from 3200 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 13:
If we divide 6080 by 648, we get 9 and a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 136796.03549
If we take 5832 away from 6080, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
When dividing 2480 by 648, we get 3 with a remainder of 536.
The next digit of our result is 3. 
Result so far: 136796.035493
Deduct 1944 from 2480 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 15:
When dividing 5360 by 648, we get 8 with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 136796.0354938
Subtracting 5184 from 5360 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
The number 648 fits into 1760 2 times, leaving a remainder of 464.
Put 2 as the next digit of the answer. 
Result so far: 136796.03549382
Subtract 1296 from 1760 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

In conclusion, the division gives 136796.03549382 with a balance of 4.64e-07.
