275113 divided by 21 
We're looking to find how many times 21 goes into 275113.

On to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 21

Going ahead to step 2:
When dividing 27 by 21, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 27 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 21

On to step 3:
21 goes into 65 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 63 from 65 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 21

Moving on to step 4:
When dividing 21 by 21, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtracting 21 from 21 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 21

Advancing to step 5:
1 divided by 21 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1310.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 21

Let's proceed to step 6:
When dividing 13 by 21, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 13100.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13100.6
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 13100.61
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 13100.619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13100.619
If we take 0 away from 10, we end up 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.

Advancing to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 13100.61904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 13100.619047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13100.6190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 13100.61904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 13100.61904761 with a remainder of 1.9e-08.
