We look at the division of 91948386 by 663 
Our goal is to divide 91948386 by 663.

Let's proceed to step 1:
663 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 663

Moving on to step 2:
91 divided by 663 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (9) from the dividend to 91 and continue with: 919 / 663

Moving on to step 3:
The number 663 fits into 919 1 times, leaving a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 663 from 919 leaves us with 256.
Grab the next digit (4) from the dividend, add it to 256, then carry on: 2564 / 663

Step 4:
If we divide 2564 by 663, we get 3 and a remainder of 575.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1989 from 2564 to get 575.
Bring next digit (8) of the dividend behind the 575 and repeat the process: 5758 / 663

Advancing to step 5:
5758 divided by 663 is 8 with a remainder of 454.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we subtract 5304 from 5758, we get 454.
Bring next digit (3) of the dividend behind the 454 and repeat the process: 4543 / 663

Going ahead to step 6:
4543 divided by 663 is 6 with a remainder of 565.
Record the quotient 6 as the next digit in the result. 
Result so far: 1386.0
Subtracting 3978 from 4543 leaves us with 565.
Append the next digit (8) from the dividend to 565 and continue with: 5658 / 663

Advancing to step 7:
663 can be fit into 5658 8 times, resulting in a remainder of 354.
The next digit of our result is 8. 
Result so far: 13868.0
Subtract 5304 from 5658 to get 354.
Bring next digit (6) of the dividend behind the 354 and repeat the process: 3546 / 663

Advancing to step 8:
3546 divided by 663 is 5 with a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 138685.0
If we take 3315 away from 3546, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

On to step 9:
When dividing 2310 by 663, we get 3 with a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 138685.3
The remainder is 321 after subtracting 1989 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 10:
When dividing 3210 by 663, we get 4 with a remainder of 558.
Write down 4 as next digit of the result. 
Result so far: 138685.34
If we take 2652 away from 3210, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 11:
If we divide 5580 by 663, we get 8 and a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 138685.348
The remainder is 276 after subtracting 5304 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 12:
The number 663 fits into 2760 4 times, leaving a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 138685.3484
If we subtract 2652 from 2760, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
The number 663 fits into 1080 1 times, leaving a remainder of 417.
Record the quotient 1 as the next digit in the result. 
Result so far: 138685.34841
If we subtract 663 from 1080, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 14:
When dividing 4170 by 663, we get 6 with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 138685.348416
Deduct 3978 from 4170 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 15:
When dividing 1920 by 663, we get 2 with a remainder of 594.
The next digit of our result is 2. 
Result so far: 138685.3484162
Subtract 1326 from 1920 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 16:
When dividing 5940 by 663, we get 8 with a remainder of 636.
Use 8 as the next digit of our solution. 
Result so far: 138685.34841628
If we take 5304 away from 5940, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 138685.34841628, with a leftover of 6.36e-07.
