We look at the division of 21720846 by 554 
We want to figure out the number of times 21720846 can be divided by 554.

Advancing to step 1:
When dividing 2 by 554, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
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 / 554

Let's proceed to step 2:
If we divide 21 by 554, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 554

Step 3:
If we divide 217 by 554, we get 0 and a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Bring next digit (2) of the dividend behind the 217 and repeat the process: 2172 / 554

Moving on to step 4:
When dividing 2172 by 554, we get 3 with a remainder of 510.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1662 from 2172 and we're left with 510.
Append the next digit (0) from the dividend to 510 and continue with: 5100 / 554

Let's proceed to step 5:
5100 divided by 554 is 9 with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 4986 from 5100, we get 114.
Take the next digit (8) from the dividend and append it to 114, then repeat: 1148 / 554

Step 6:
When dividing 1148 by 554, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 392.0
If we take 1108 away from 1148, we end up with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 554

Advancing to step 7:
When dividing 404 by 554, we get 0 with a remainder of 404.
Write down 0 as next digit of the result. 
Result so far: 3920.0
If we subtract 0 from 404, we get 404.
Fetch the next digit (6) from the dividend, attach it to 404 and continue: 4046 / 554

Advancing to step 8:
4046 divided by 554 is 7 with a remainder of 168.
Write down 7 as next digit of the result. 
Result so far: 39207.0
Deduct 3878 from 4046 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
1680 divided by 554 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 39207.3
Subtracting 1662 from 1680 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
554 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 39207.3
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
1800 divided by 554 is 3 with a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 39207.303
Deduct 1662 from 1800 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.

Step 12:
When dividing 1380 by 554, we get 2 with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 39207.3032
If we subtract 1108 from 1380, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
554 goes into 2720 4 times with a remainder of 504.
Use 4 as the next digit of our solution. 
Result so far: 39207.30324
Deduct 2216 from 2720 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 14:
554 goes into 5040 9 times with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 39207.303249
Subtracting 4986 from 5040 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 15:
If we divide 540 by 554, we get 0 and a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 39207.303249
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 16:
5400 divided by 554 is 9 with a remainder of 414.
Put 9 as the next digit of the answer. 
Result so far: 39207.30324909
Deduct 4986 from 5400 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 39207.30324909 with a remainder of 4.14e-07.
