20979938 ÷ 848 
Let's see how many times 848 fits into 20979938.

Going ahead to step 1:
848 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 848

Going ahead to step 2:
If we divide 20 by 848, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 848

Going ahead to step 3:
The number 848 fits into 209 0 times, leaving a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Grab the next digit (7) from the dividend, add it to 209, then carry on: 2097 / 848

Moving on to step 4:
The number 848 fits into 2097 2 times, leaving a remainder of 401.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1696 from 2097 leaves us with 401.
Take the next digit (9) from the dividend and append it to 401, then repeat: 4019 / 848

On to step 5:
848 can be fit into 4019 4 times, resulting in a remainder of 627.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 3392 from 4019, we get 627.
Append the next digit (9) from the dividend to 627 and continue with: 6279 / 848

Moving on to step 6:
When dividing 6279 by 848, we get 7 with a remainder of 343.
The next digit of our result is 7. 
Result so far: 247.0
If we take 5936 away from 6279, we end up with 343.
Fetch the next digit (3) from the dividend, attach it to 343 and continue: 3433 / 848

Going ahead to step 7:
If we divide 3433 by 848, we get 4 and a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 2474.0
Subtract 3392 from 3433 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 848

Going ahead to step 8:
If we divide 418 by 848, we get 0 and a remainder of 418.
Put 0 as the next digit of the answer. 
Result so far: 24740.0
If we subtract 0 from 418, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 9:
4180 divided by 848 is 4 with a remainder of 788.
Use 4 as the next digit of our solution. 
Result so far: 24740.4
If we take 3392 away from 4180, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Moving on to step 10:
848 goes into 7880 9 times with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 24740.49
Subtracting 7632 from 7880 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 11:
The number 848 fits into 2480 2 times, leaving a remainder of 784.
Use 2 as the next digit of our solution. 
Result so far: 24740.492
Subtract 1696 from 2480 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 12:
When dividing 7840 by 848, we get 9 with a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 24740.4929
Subtracting 7632 from 7840 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
The number 848 fits into 2080 2 times, leaving a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 24740.49292
Deduct 1696 from 2080 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
If we divide 3840 by 848, we get 4 and a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 24740.492924
Subtract 3392 from 3840 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 15:
4480 divided by 848 is 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 24740.4929245
Subtract 4240 from 4480 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
848 can be fit into 2400 2 times, resulting in a remainder of 704.
Write down 2 as next digit of the result. 
Result so far: 24740.49292452
Subtracting 1696 from 2400 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final result is 24740.49292452 with a remainder of 7.04e-07.
