We look at the division of 27921 by 89 
We want to figure out the number of times 27921 can be divided by 89.

On to step 1:
If we divide 2 by 89, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 89

Step 2:
When dividing 27 by 89, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 89

Advancing to step 3:
89 goes into 279 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
If we take 267 away from 279, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 89

Step 4:
89 can be fit into 122 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 89 from 122 to get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 89

Let's proceed to step 5:
89 goes into 331 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 313.0
If we subtract 267 from 331, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 6:
If we divide 640 by 89, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 313.7
The remainder is 17 after subtracting 623 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 89 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 313.71
Subtract 89 from 170 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
The number 89 fits into 810 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 313.719
Subtracting 801 from 810 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 89, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 313.7191
Subtract 89 from 90 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
The number 89 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 313.7191
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 89, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 313.719101
Deduct 89 from 100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
89 can be fit into 110 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 313.7191011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 313.7191011 and a remainder of 2.1e-07.
