21015226 ÷ 554 
Our goal is to divide 21015226 by 554.

Let's proceed to step 1:
2 divided by 554 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 554

Step 2:
21 divided by 554 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 554

Let's proceed to step 3:
554 can be fit into 210 0 times, resulting in a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 210, we get 210.
Include the next digit (1) from the dividend after 210, then repeat: 2101 / 554

On to step 4:
2101 divided by 554 is 3 with a remainder of 439.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1662 from 2101, we get 439.
Include the next digit (5) from the dividend after 439, then repeat: 4395 / 554

Going ahead to step 5:
4395 divided by 554 is 7 with a remainder of 517.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 3878 away from 4395, we end up with 517.
Fetch the next digit (2) from the dividend, attach it to 517 and continue: 5172 / 554

Advancing to step 6:
The number 554 fits into 5172 9 times, leaving a remainder of 186.
The next digit of our result is 9. 
Result so far: 379.0
The remainder is 186 after subtracting 4986 from 5172.
Fetch the next digit (2) from the dividend, attach it to 186 and continue: 1862 / 554

Moving on to step 7:
When dividing 1862 by 554, we get 3 with a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 3793.0
If we take 1662 away from 1862, we end up with 200.
Append the next digit (6) from the dividend to 200 and continue with: 2006 / 554

Step 8:
If we divide 2006 by 554, we get 3 and a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 37933.0
If we subtract 1662 from 2006, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 9:
554 goes into 3440 6 times with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 37933.6
The remainder is 116 after subtracting 3324 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
1160 divided by 554 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 37933.62
If we take 1108 away from 1160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 554, we get 0 with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 37933.62
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
If we divide 5200 by 554, we get 9 and a remainder of 214.
Put 9 as the next digit of the answer. 
Result so far: 37933.6209
Deduct 4986 from 5200 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 13:
When dividing 2140 by 554, we get 3 with a remainder of 478.
Write down 3 as next digit of the result. 
Result so far: 37933.62093
The remainder is 478 after subtracting 1662 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 14:
If we divide 4780 by 554, we get 8 and a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 37933.620938
If we subtract 4432 from 4780, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 15:
554 goes into 3480 6 times with a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 37933.6209386
If we subtract 3324 from 3480, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 16:
554 can be fit into 1560 2 times, resulting in a remainder of 452.
Record the quotient 2 as the next digit in the result. 
Result so far: 37933.62093862
If we subtract 1108 from 1560, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The quotient of the division is 37933.62093862, and the remainder is 4.52e-07.
