997399 ÷ 99 
We're looking to find how many times 99 goes into 997399.

On to step 1:
If we divide 9 by 99, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 99

Moving on to step 2:
If we divide 99 by 99, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 99 away from 99, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 99

Let's proceed to step 3:
99 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 99

Going ahead to step 4:
99 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 73, we end up with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 99

Advancing to step 5:
If we divide 739 by 99, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 1007.0
Deduct 693 from 739 and we're left with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 99

Going ahead to step 6:
469 divided by 99 is 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 10074.0
Subtracting 396 from 469 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
99 goes into 730 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 10074.7
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
The number 99 fits into 370 3 times, leaving a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 10074.73
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
730 divided by 99 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 10074.737
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
When dividing 370 by 99, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 10074.7373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
730 divided by 99 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 10074.73737
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 99, we get 3 and a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 10074.737373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
When dividing 730 by 99, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 10074.7373737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
When dividing 370 by 99, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 10074.73737373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 10074.73737373, with a leftover of 7.3e-08.
