21792 divided by 70 
Let's see how many times 70 fits into 21792.

Going ahead to step 1:
70 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 70

Going ahead to step 2:
The number 70 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 70

Going ahead to step 3:
217 divided by 70 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 210 from 217 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 70

Let's proceed to step 4:
The number 70 fits into 79 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 70 from 79 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 70

On to step 5:
If we divide 92 by 70, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 311.0
Deduct 70 from 92 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
70 goes into 220 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 311.3
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
70 goes into 100 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 311.31
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 311.314
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 311.3142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 311.31428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 311.314285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 311.3142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 311.31428571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 311.31428571 with a remaining 3e-08.
