We divide 27100070 by 21
We're looking to find how many times 21 goes into 27100070.

Advancing to step 1:
21 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 21

Let's proceed to step 2:
27 divided by 21 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 27 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 21

Moving on to step 3:
21 can be fit into 61 2 times, resulting in a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 42 from 61, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 21

Advancing to step 4:
21 goes into 190 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we take 189 away from 190, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 21

Let's proceed to step 5:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1290.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 21

Advancing to step 6:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 12904.0
Deduct 84 from 100 and we're left with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 21

Step 7:
167 divided by 21 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 129047.0
If we subtract 147 from 167, we get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 21

Moving on to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1290479.0
If we take 189 away from 200, we end up 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.

On to step 9:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1290479.5
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1290479.52
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1290479.523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1290479.5238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1290479.5238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1290479.523809
If we subtract 189 from 200, we get 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 15:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1290479.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 1290479.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1290479.52380952, and the remainder is 8e-09.
