Fetch the next digit (2) from the dividend, attach it to 776 and continue: 7762 / 993

Step 4:
The number 993 fits into 7762 7 times, leaving a remainder of 811.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6951 from 7762 to get 811.
Append the next digit (6) from the dividend to 811 and continue with: 8116 / 993

On to step 5:
When dividing 8116 by 993, we get 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 172 after subtracting 7944 from 8116.
Take the next digit (3) from the dividend and append it to 172, then repeat: 1723 / 993

Moving on to step 6:
993 goes into 1723 1 times with a remainder of 730.
Put 1 as the next digit of the answer. 
Result so far: 781.0
Subtract 993 from 1723 to get 730.
Fetch the next digit (2) from the dividend, attach it to 730 and continue: 7302 / 993

Moving on to step 7:
7302 divided by 993 is 7 with a remainder of 351.
Record the quotient 7 as the next digit in the result. 
Result so far: 7817.0
Subtract 6951 from 7302 to get 351.
Fetch the next digit (0) from the dividend, attach it to 351 and continue: 3510 / 993

Advancing to step 8:
The number 993 fits into 3510 3 times, leaving a remainder of 531.
The next digit of our result is 3. 
Result so far: 78173.0
Deduct 2979 from 3510 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Advancing to step 9:
If we divide 5310 by 993, we get 5 and a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 78173.5
If we take 4965 away from 5310, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 10:
993 goes into 3450 3 times with a remainder of 471.
Put 3 as the next digit of the answer. 
Result so far: 78173.53
If we take 2979 away from 3450, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 11:
993 goes into 4710 4 times with a remainder of 738.
Use 4 as the next digit of our solution. 
Result so far: 78173.534
Subtract 3972 from 4710 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Advancing to step 12:
If we divide 7380 by 993, we get 7 and a remainder of 429.
The next digit of our result is 7. 
Result so far: 78173.5347
Deduct 6951 from 7380 and we're left with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 13:
993 can be fit into 4290 4 times, resulting in a remainder of 318.
Put 4 as the next digit of the answer. 
Result so far: 78173.53474
Deduct 3972 from 4290 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 14:
993 goes into 3180 3 times with a remainder of 201.
Write down 3 as next digit of the result. 
Result so far: 78173.534743
The remainder is 201 after subtracting 2979 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 15:
The number 993 fits into 2010 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 78173.5347432
Deduct 1986 from 2010 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 16:
993 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 78173.5347432
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 78173.5347432 with a remaining 2.4e-07.
