Let's divide 91643058 by 993
We're looking to find how many times 993 goes into 91643058.

Step 1:
993 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 993

Advancing to step 2:
91 divided by 993 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 993

Advancing to step 3:
If we divide 916 by 993, we get 0 and a remainder of 916.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 916 and we're left with 916.
Fetch the next digit (4) from the dividend, attach it to 916 and continue: 9164 / 993

Going ahead to step 4:
993 can be fit into 9164 9 times, resulting in a remainder of 227.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 227 after subtracting 8937 from 9164.
Take the next digit (3) from the dividend and append it to 227, then repeat: 2273 / 993

Step 5:
The number 993 fits into 2273 2 times, leaving a remainder of 287.
The next digit of our result is 2. 
Result so far: 92.0
If we take 1986 away from 2273, we end up with 287.
Include the next digit (0) from the dividend after 287, then repeat: 2870 / 993

On to step 6:
If we divide 2870 by 993, we get 2 and a remainder of 884.
The number 2 becomes the next digit in our result. 
Result so far: 922.0
Deduct 1986 from 2870 and we're left with 884.
Take the next digit (5) from the dividend and append it to 884, then repeat: 8845 / 993

On to step 7:
If we divide 8845 by 993, we get 8 and a remainder of 901.
The number 8 becomes the next digit in our result. 
Result so far: 9228.0
Subtracting 7944 from 8845 leaves us with 901.
Grab the next digit (8) from the dividend, add it to 901, then carry on: 9018 / 993

On to step 8:
The number 993 fits into 9018 9 times, leaving a remainder of 81.
The next digit of our result is 9. 
Result so far: 92289.0
The remainder is 81 after subtracting 8937 from 9018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
993 goes into 810 0 times with a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 92289.0
The remainder is 810 after subtracting 0 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 10:
The number 993 fits into 8100 8 times, leaving a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 92289.08
Subtracting 7944 from 8100 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
When dividing 1560 by 993, we get 1 with a remainder of 567.
The next digit of our result is 1. 
Result so far: 92289.081
If we subtract 993 from 1560, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 12:
993 can be fit into 5670 5 times, resulting in a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 92289.0815
Subtract 4965 from 5670 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Moving on to step 13:
The number 993 fits into 7050 7 times, leaving a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 92289.08157
If we subtract 6951 from 7050, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 14:
990 divided by 993 is 0 with a remainder of 990.
Write down 0 as next digit of the result. 
Result so far: 92289.08157
If we take 0 away from 990, we end up with 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9900, and continue the process.

Advancing to step 15:
9900 divided by 993 is 9 with a remainder of 963.
The number 9 becomes the next digit in our result. 
Result so far: 92289.0815709
Subtract 8937 from 9900 to get 963.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9630, and continue the process.

Going ahead to step 16:
If we divide 9630 by 993, we get 9 and a remainder of 693.
The next digit of our result is 9. 
Result so far: 92289.08157099
If we take 8937 away from 9630, we end up with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

The final result is 92289.08157099 with a remainder of 6.93e-07.
