637207 ÷ 99 
We're looking to find how many times 99 goes into 637207.

Step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 99

Moving on to step 2:
99 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 99

Advancing to step 3:
637 divided by 99 is 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 43 after subtracting 594 from 637.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 99

On to step 4:
The number 99 fits into 432 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we take 396 away from 432, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 99

Going ahead to step 5:
99 goes into 360 3 times with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 643.0
If we subtract 297 from 360, we get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 99

Let's proceed to step 6:
When dividing 637 by 99, we get 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6436.0
If we take 594 away from 637, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
The number 99 fits into 430 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 6436.4
If we subtract 396 from 430, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
99 goes into 340 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 6436.43
The remainder is 43 after subtracting 297 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
If we divide 430 by 99, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 6436.434
If we subtract 396 from 430, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 99, we get 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 6436.4343
Subtract 297 from 340 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
99 goes into 430 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 6436.43434
If we take 396 away from 430, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
The number 99 fits into 340 3 times, leaving a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 6436.434343
If we subtract 297 from 340, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
430 divided by 99 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 6436.4343434
Subtracting 396 from 430 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
When dividing 340 by 99, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 6436.43434343
Deduct 297 from 340 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 6436.43434343 with a remainder of 4.3e-08.
