Let's divide 81991 by 7
We want to figure out the number of times 81991 can be divided by 7.

Moving on to step 1:
7 goes into 8 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

Advancing to step 2:
7 can be fit into 11 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 7 from 11, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 7

Let's proceed to step 3:
When dividing 49 by 7, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 117.0
If we take 49 away from 49, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 7

Moving on to step 4:
If we divide 9 by 7, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1171.0
If we subtract 7 from 9, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 7

Let's proceed to step 5:
21 divided by 7 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 11713.0
Subtracting 21 from 21 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11713.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11713.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 11713.0, and the remainder is 0.0.
