We look at the division of 21098063 by 401 
We're looking to find how many times 401 goes into 21098063.

Advancing to step 1:
When dividing 2 by 401, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 401

Going ahead to step 2:
21 divided by 401 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 401

Let's proceed to step 3:
If we divide 210 by 401, we get 0 and a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Append the next digit (9) from the dividend to 210 and continue with: 2109 / 401

On to step 4:
When dividing 2109 by 401, we get 5 with a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 2005 from 2109, we get 104.
Include the next digit (8) from the dividend after 104, then repeat: 1048 / 401

Step 5:
1048 divided by 401 is 2 with a remainder of 246.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 802 from 1048 leaves us with 246.
Append the next digit (0) from the dividend to 246 and continue with: 2460 / 401

Going ahead to step 6:
2460 divided by 401 is 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 526.0
If we take 2406 away from 2460, we end up with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 401

Going ahead to step 7:
546 divided by 401 is 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 5261.0
Subtract 401 from 546 to get 145.
Fetch the next digit (3) from the dividend, attach it to 145 and continue: 1453 / 401

Let's proceed to step 8:
1453 divided by 401 is 3 with a remainder of 250.
The next digit of our result is 3. 
Result so far: 52613.0
If we take 1203 away from 1453, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 9:
2500 divided by 401 is 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 52613.6
Deduct 2406 from 2500 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
401 can be fit into 940 2 times, resulting in a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 52613.62
Deduct 802 from 940 and we're left 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 11:
If we divide 1380 by 401, we get 3 and a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 52613.623
The remainder is 177 after subtracting 1203 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 12:
The number 401 fits into 1770 4 times, leaving a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 52613.6234
If we take 1604 away from 1770, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 13:
401 goes into 1660 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 52613.62344
The remainder is 56 after subtracting 1604 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 52613.62344 with a balance of 5.6e-05.
