We're dividing 21352851 by 313 
We want to divide 21352851 by 313.

Let's proceed to step 1:
313 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
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 313

Moving on to step 2:
When dividing 21 by 313, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 313

Let's proceed to step 3:
313 can be fit into 213 0 times, resulting in a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Include the next digit (5) from the dividend after 213, then repeat: 2135 / 313

Let's proceed to step 4:
The number 313 fits into 2135 6 times, leaving a remainder of 257.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 257 after subtracting 1878 from 2135.
Fetch the next digit (2) from the dividend, attach it to 257 and continue: 2572 / 313

Advancing to step 5:
2572 divided by 313 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 2504 from 2572 leaves us with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 313

On to step 6:
313 can be fit into 688 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 682.0
Subtract 626 from 688 to get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 313

Going ahead to step 7:
If we divide 625 by 313, we get 1 and a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 6821.0
Deduct 313 from 625 and we're left with 312.
Append the next digit (1) from the dividend to 312 and continue with: 3121 / 313

Going ahead to step 8:
If we divide 3121 by 313, we get 9 and a remainder of 304.
Record the quotient 9 as the next digit in the result. 
Result so far: 68219.0
Subtract 2817 from 3121 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
313 goes into 3040 9 times with a remainder of 223.
Record the quotient 9 as the next digit in the result. 
Result so far: 68219.9
The remainder is 223 after subtracting 2817 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 10:
The number 313 fits into 2230 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 68219.97
If we subtract 2191 from 2230, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
When dividing 390 by 313, we get 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 68219.971
Deduct 313 from 390 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 12:
The number 313 fits into 770 2 times, leaving a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 68219.9712
If we subtract 626 from 770, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
313 goes into 1440 4 times with a remainder of 188.
Record the quotient 4 as the next digit in the result. 
Result so far: 68219.97124
If we subtract 1252 from 1440, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 14:
1880 divided by 313 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 68219.971246
Deduct 1878 from 1880 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
20 divided by 313 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 68219.971246
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
313 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 68219.971246
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 68219.971246 with a balance of 2e-07.
