We're dividing 63747452 by 643 
We want to figure out the number of times 63747452 can be divided by 643.

Let's proceed to step 1:
When dividing 6 by 643, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 643

On to step 2:
The number 643 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 643

Step 3:
643 can be fit into 637 0 times, resulting in a remainder of 637.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 637, we end up with 637.
Include the next digit (4) from the dividend after 637, then repeat: 6374 / 643

Let's proceed to step 4:
643 goes into 6374 9 times with a remainder of 587.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 5787 from 6374 leaves us with 587.
Grab the next digit (7) from the dividend, add it to 587, then carry on: 5877 / 643

Going ahead to step 5:
643 can be fit into 5877 9 times, resulting in a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 90 after subtracting 5787 from 5877.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 643

Let's proceed to step 6:
When dividing 904 by 643, we get 1 with a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 991.0
The remainder is 261 after subtracting 643 from 904.
Bring next digit (5) of the dividend behind the 261 and repeat the process: 2615 / 643

Let's proceed to step 7:
643 goes into 2615 4 times with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 9914.0
The remainder is 43 after subtracting 2572 from 2615.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 643

Going ahead to step 8:
643 can be fit into 432 0 times, resulting in a remainder of 432.
Record the quotient 0 as the next digit in the result. 
Result so far: 99140.0
Subtracting 0 from 432 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 9:
When dividing 4320 by 643, we get 6 with a remainder of 462.
Use 6 as the next digit of our solution. 
Result so far: 99140.6
Subtracting 3858 from 4320 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 10:
When dividing 4620 by 643, we get 7 with a remainder of 119.
The next digit of our result is 7. 
Result so far: 99140.67
If we take 4501 away from 4620, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 11:
643 goes into 1190 1 times with a remainder of 547.
Put 1 as the next digit of the answer. 
Result so far: 99140.671
Subtracting 643 from 1190 leaves us with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Let's proceed to step 12:
The number 643 fits into 5470 8 times, leaving a remainder of 326.
Write down 8 as next digit of the result. 
Result so far: 99140.6718
If we subtract 5144 from 5470, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 13:
If we divide 3260 by 643, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 99140.67185
If we take 3215 away from 3260, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
When dividing 450 by 643, we get 0 with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 99140.67185
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
643 can be fit into 4500 6 times, resulting in a remainder of 642.
The number 6 becomes the next digit in our result. 
Result so far: 99140.6718506
Subtract 3858 from 4500 to get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 16:
643 goes into 6420 9 times with a remainder of 633.
The next digit of our result is 9. 
Result so far: 99140.67185069
Deduct 5787 from 6420 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

After the division, we end up with 99140.67185069 and a remainder of 6.33e-07.
