642252 divided by 99 
Let's see how many times 99 fits into 642252.

Moving on to step 1:
99 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 99

Moving on to step 2:
If we divide 64 by 99, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 99

Let's proceed to step 3:
The number 99 fits into 642 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 594 from 642 leaves us with 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 99

Advancing to step 4:
99 goes into 482 4 times with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 396 away from 482, we end up with 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 99

Step 5:
99 goes into 865 8 times with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
If we take 792 away from 865, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 99

Advancing to step 6:
If we divide 732 by 99, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 6487.0
If we take 693 away from 732, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 99 fits into 390 3 times, leaving a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 6487.3
The remainder is 93 after subtracting 297 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 8:
When dividing 930 by 99, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 6487.39
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 99, we get 3 with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 6487.393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 10:
When dividing 930 by 99, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 6487.3939
Deduct 891 from 930 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
99 goes into 390 3 times with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 6487.39393
The remainder is 93 after subtracting 297 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 12:
99 goes into 930 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 6487.393939
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
If we divide 390 by 99, we get 3 and a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 6487.3939393
Deduct 297 from 390 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 14:
If we divide 930 by 99, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 6487.39393939
Deduct 891 from 930 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 6487.39393939 with a remainder of 3.9e-08.
