We look at the division of 21862492 by 688 
Our goal is to divide 21862492 by 688.

Step 1:
2 divided by 688 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 688

Advancing to step 2:
If we divide 21 by 688, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 688

Moving on to step 3:
688 goes into 218 0 times with a remainder of 218.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 688

Advancing to step 4:
The number 688 fits into 2186 3 times, leaving a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2064 from 2186, we get 122.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 688

Let's proceed to step 5:
688 goes into 1222 1 times with a remainder of 534.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 688 away from 1222, we end up with 534.
Grab the next digit (4) from the dividend, add it to 534, then carry on: 5344 / 688

Moving on to step 6:
The number 688 fits into 5344 7 times, leaving a remainder of 528.
Use 7 as the next digit of our solution. 
Result so far: 317.0
Deduct 4816 from 5344 and we're left with 528.
Fetch the next digit (9) from the dividend, attach it to 528 and continue: 5289 / 688

On to step 7:
When dividing 5289 by 688, we get 7 with a remainder of 473.
The next digit of our result is 7. 
Result so far: 3177.0
If we subtract 4816 from 5289, we get 473.
Bring next digit (2) of the dividend behind the 473 and repeat the process: 4732 / 688

On to step 8:
688 goes into 4732 6 times with a remainder of 604.
Record the quotient 6 as the next digit in the result. 
Result so far: 31776.0
If we take 4128 away from 4732, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 9:
688 goes into 6040 8 times with a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 31776.8
Deduct 5504 from 6040 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 10:
688 can be fit into 5360 7 times, resulting in a remainder of 544.
Use 7 as the next digit of our solution. 
Result so far: 31776.87
The remainder is 544 after subtracting 4816 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 11:
When dividing 5440 by 688, we get 7 with a remainder of 624.
The next digit of our result is 7. 
Result so far: 31776.877
Subtracting 4816 from 5440 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

After the division, we end up with 31776.877 and a remainder of 0.0624.
