We look at the division of 21921233 by 388 
We want to figure out the number of times 21921233 can be divided by 388.

Step 1:
388 goes into 2 0 times with 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 388

Let's proceed to step 2:
388 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 388

Let's proceed to step 3:
When dividing 219 by 388, we get 0 with a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 219 to get 219.
Include the next digit (2) from the dividend after 219, then repeat: 2192 / 388

On to step 4:
2192 divided by 388 is 5 with a remainder of 252.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1940 from 2192 and we're left with 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 388

Advancing to step 5:
The number 388 fits into 2521 6 times, leaving a remainder of 193.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 2328 from 2521 leaves us with 193.
Fetch the next digit (2) from the dividend, attach it to 193 and continue: 1932 / 388

Let's proceed to step 6:
388 goes into 1932 4 times with a remainder of 380.
Put 4 as the next digit of the answer. 
Result so far: 564.0
The remainder is 380 after subtracting 1552 from 1932.
Fetch the next digit (3) from the dividend, attach it to 380 and continue: 3803 / 388

Advancing to step 7:
When dividing 3803 by 388, we get 9 with a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 5649.0
The remainder is 311 after subtracting 3492 from 3803.
Include the next digit (3) from the dividend after 311, then repeat: 3113 / 388

Advancing to step 8:
388 goes into 3113 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 56498.0
Deduct 3104 from 3113 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
388 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 56498.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
When dividing 900 by 388, we get 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 56498.02
If we take 776 away from 900, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
388 can be fit into 1240 3 times, resulting in a remainder of 76.
The next digit of our result is 3. 
Result so far: 56498.023
The remainder is 76 after subtracting 1164 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
When dividing 760 by 388, we get 1 with a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 56498.0231
If we subtract 388 from 760, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
388 can be fit into 3720 9 times, resulting in a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 56498.02319
Deduct 3492 from 3720 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 14:
The number 388 fits into 2280 5 times, leaving a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 56498.023195
The remainder is 340 after subtracting 1940 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 15:
The number 388 fits into 3400 8 times, leaving a remainder of 296.
The next digit of our result is 8. 
Result so far: 56498.0231958
If we subtract 3104 from 3400, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 16:
If we divide 2960 by 388, we get 7 and a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 56498.02319587
If we take 2716 away from 2960, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 56498.02319587 with a remainder of 2.44e-07.
