83997349 divided by 663 
We're looking to find how many times 663 goes into 83997349.

Step 1:
8 divided by 663 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 663

Moving on to step 2:
663 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 663

Going ahead to step 3:
663 goes into 839 1 times with a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 663 from 839 leaves us with 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 663

Moving on to step 4:
663 goes into 1769 2 times with a remainder of 443.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1326 from 1769 to get 443.
Grab the next digit (7) from the dividend, add it to 443, then carry on: 4437 / 663

Step 5:
663 can be fit into 4437 6 times, resulting in a remainder of 459.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 3978 away from 4437, we end up with 459.
Append the next digit (3) from the dividend to 459 and continue with: 4593 / 663

Advancing to step 6:
The number 663 fits into 4593 6 times, leaving a remainder of 615.
Put 6 as the next digit of the answer. 
Result so far: 1266.0
Deduct 3978 from 4593 and we're left with 615.
Fetch the next digit (4) from the dividend, attach it to 615 and continue: 6154 / 663

Moving on to step 7:
663 goes into 6154 9 times with a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 12669.0
If we subtract 5967 from 6154, we get 187.
Grab the next digit (9) from the dividend, add it to 187, then carry on: 1879 / 663

Let's proceed to step 8:
663 goes into 1879 2 times with a remainder of 553.
The next digit of our result is 2. 
Result so far: 126692.0
Subtract 1326 from 1879 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
5530 divided by 663 is 8 with a remainder of 226.
The next digit of our result is 8. 
Result so far: 126692.8
If we take 5304 away from 5530, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
The number 663 fits into 2260 3 times, leaving a remainder of 271.
The next digit of our result is 3. 
Result so far: 126692.83
If we subtract 1989 from 2260, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 11:
If we divide 2710 by 663, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 126692.834
Subtracting 2652 from 2710 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
When dividing 580 by 663, we get 0 with a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 126692.834
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 13:
663 can be fit into 5800 8 times, resulting in a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 126692.83408
Subtract 5304 from 5800 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 14:
If we divide 4960 by 663, we get 7 and a remainder of 319.
The next digit of our result is 7. 
Result so far: 126692.834087
If we take 4641 away from 4960, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 15:
663 can be fit into 3190 4 times, resulting in a remainder of 538.
The next digit of our result is 4. 
Result so far: 126692.8340874
Subtract 2652 from 3190 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 16:
5380 divided by 663 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 126692.83408748
Subtracting 5304 from 5380 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 126692.83408748 with a balance of 7.6e-08.
