We look at the division of 21949602 by 398 
We want to figure out the number of times 21949602 can be divided by 398.

Moving on to step 1:
2 divided by 398 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 398

On to step 2:
The number 398 fits into 21 0 times, leaving 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.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 398

Advancing to step 3:
398 goes into 219 0 times with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Grab the next digit (4) from the dividend, add it to 219, then carry on: 2194 / 398

On to step 4:
2194 divided by 398 is 5 with a remainder of 204.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 1990 from 2194 to get 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 398

Step 5:
398 can be fit into 2049 5 times, resulting in a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 1990 from 2049 to get 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 398

Advancing to step 6:
When dividing 596 by 398, we get 1 with a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 551.0
Subtracting 398 from 596 leaves us with 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 398

Let's proceed to step 7:
The number 398 fits into 1980 4 times, leaving a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 5514.0
Deduct 1592 from 1980 and we're left with 388.
Fetch the next digit (2) from the dividend, attach it to 388 and continue: 3882 / 398

Advancing to step 8:
398 can be fit into 3882 9 times, resulting in a remainder of 300.
Use 9 as the next digit of our solution. 
Result so far: 55149.0
If we subtract 3582 from 3882, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
398 can be fit into 3000 7 times, resulting in a remainder of 214.
Record the quotient 7 as the next digit in the result. 
Result so far: 55149.7
If we subtract 2786 from 3000, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 10:
When dividing 2140 by 398, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 55149.75
Subtracting 1990 from 2140 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
When dividing 1500 by 398, we get 3 with a remainder of 306.
The next digit of our result is 3. 
Result so far: 55149.753
Subtract 1194 from 1500 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 12:
When dividing 3060 by 398, we get 7 with a remainder of 274.
The next digit of our result is 7. 
Result so far: 55149.7537
Deduct 2786 from 3060 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 13:
398 goes into 2740 6 times with a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 55149.75376
The remainder is 352 after subtracting 2388 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 14:
The number 398 fits into 3520 8 times, leaving a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 55149.753768
The remainder is 336 after subtracting 3184 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 15:
The number 398 fits into 3360 8 times, leaving a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 55149.7537688
Deduct 3184 from 3360 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 55149.7537688 with a balance of 1.76e-06.
