We look at the division of 21455198 by 379 
Our goal is to divide 21455198 by 379.

Let's proceed to step 1:
2 divided by 379 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 379

Step 2:
The number 379 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 379

Step 3:
The number 379 fits into 214 0 times, leaving a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 379

Moving on to step 4:
When dividing 2145 by 379, we get 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 1895 away from 2145, we end up with 250.
Include the next digit (5) from the dividend after 250, then repeat: 2505 / 379

Moving on to step 5:
If we divide 2505 by 379, we get 6 and a remainder of 231.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we take 2274 away from 2505, we end up with 231.
Grab the next digit (1) from the dividend, add it to 231, then carry on: 2311 / 379

On to step 6:
379 goes into 2311 6 times with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 566.0
Deduct 2274 from 2311 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 379

Step 7:
379 goes into 379 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 5661.0
Deduct 379 from 379 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 379

Going ahead to step 8:
When dividing 8 by 379, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 56610.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
379 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 56610.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
379 can be fit into 800 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 56610.02
If we take 758 away from 800, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
When dividing 420 by 379, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 56610.021
Subtract 379 from 420 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
379 goes into 410 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 56610.0211
If we subtract 379 from 410, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 56610.0211, and the remainder is 0.00031.
