21246981 ÷ 247 
We're looking to find how many times 247 goes into 21246981.

Advancing to step 1:
When dividing 2 by 247, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 247

Advancing to step 2:
If we divide 21 by 247, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 247

On to step 3:
247 goes into 212 0 times with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Append the next digit (4) from the dividend to 212 and continue with: 2124 / 247

Let's proceed to step 4:
When dividing 2124 by 247, we get 8 with a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 1976 from 2124 to get 148.
Grab the next digit (6) from the dividend, add it to 148, then carry on: 1486 / 247

Step 5:
1486 divided by 247 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 1482 from 1486 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 247

Step 6:
247 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 860.0
If we subtract 0 from 49, we get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 247

Step 7:
247 can be fit into 498 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 8602.0
Subtracting 494 from 498 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 247

Going ahead to step 8:
247 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 86020.0
Deduct 0 from 41 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
247 can be fit into 410 1 times, resulting in a remainder of 163.
Put 1 as the next digit of the answer. 
Result so far: 86020.1
Subtracting 247 from 410 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 10:
1630 divided by 247 is 6 with a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 86020.16
Deduct 1482 from 1630 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
1480 divided by 247 is 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 86020.165
If we subtract 1235 from 1480, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 12:
When dividing 2450 by 247, we get 9 with a remainder of 227.
Record the quotient 9 as the next digit in the result. 
Result so far: 86020.1659
If we subtract 2223 from 2450, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 13:
247 goes into 2270 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 86020.16599
Subtracting 2223 from 2270 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 86020.16599 with a remaining 4.7e-05.
