21206362 ÷ 688 
We're looking to find how many times 688 goes into 21206362.

Let's proceed to step 1:
688 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 688

Advancing to step 2:
688 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 688

Step 3:
The number 688 fits into 212 0 times, leaving a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Bring next digit (0) of the dividend behind the 212 and repeat the process: 2120 / 688

Step 4:
If we divide 2120 by 688, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 56 after subtracting 2064 from 2120.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 688

Moving on to step 5:
The number 688 fits into 566 0 times, leaving a remainder of 566.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 566, we get 566.
Grab the next digit (3) from the dividend, add it to 566, then carry on: 5663 / 688

Going ahead to step 6:
688 can be fit into 5663 8 times, resulting in a remainder of 159.
Use 8 as the next digit of our solution. 
Result so far: 308.0
Subtract 5504 from 5663 to get 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 688

Moving on to step 7:
The number 688 fits into 1596 2 times, leaving a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 3082.0
Subtract 1376 from 1596 to get 220.
Grab the next digit (2) from the dividend, add it to 220, then carry on: 2202 / 688

Step 8:
If we divide 2202 by 688, we get 3 and a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 30823.0
If we take 2064 away from 2202, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
If we divide 1380 by 688, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 30823.2
If we take 1376 away from 1380, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
688 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 30823.2
Subtract 0 from 40 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 688 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 30823.2
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 30823.2, and the remainder is 0.04.
