We're dividing 21987898 by 353 
We want to figure out the number of times 21987898 can be divided by 353.

On to step 1:
353 goes into 2 0 times with 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 353

Going ahead to step 2:
353 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 353

Going ahead to step 3:
If we divide 219 by 353, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Grab the next digit (8) from the dividend, add it to 219, then carry on: 2198 / 353

Advancing to step 4:
When dividing 2198 by 353, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 2118 from 2198 and we're left with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 353

Advancing to step 5:
The number 353 fits into 807 2 times, leaving a remainder of 101.
The next digit of our result is 2. 
Result so far: 62.0
Subtracting 706 from 807 leaves us with 101.
Bring next digit (8) of the dividend behind the 101 and repeat the process: 1018 / 353

Let's proceed to step 6:
1018 divided by 353 is 2 with a remainder of 312.
The next digit of our result is 2. 
Result so far: 622.0
Subtract 706 from 1018 to get 312.
Take the next digit (9) from the dividend and append it to 312, then repeat: 3129 / 353

Going ahead to step 7:
The number 353 fits into 3129 8 times, leaving a remainder of 305.
The number 8 becomes the next digit in our result. 
Result so far: 6228.0
The remainder is 305 after subtracting 2824 from 3129.
Append the next digit (8) from the dividend to 305 and continue with: 3058 / 353

Let's proceed to step 8:
353 can be fit into 3058 8 times, resulting in a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 62288.0
Deduct 2824 from 3058 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 9:
353 can be fit into 2340 6 times, resulting in a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 62288.6
If we take 2118 away from 2340, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
The number 353 fits into 2220 6 times, leaving a remainder of 102.
The next digit of our result is 6. 
Result so far: 62288.66
The remainder is 102 after subtracting 2118 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 62288.66, and the remainder is 0.102.
