We look at the division of 21404607 by 554 
We're looking to find how many times 554 goes into 21404607.

Step 1:
554 goes into 2 0 times 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 554

Step 2:
554 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 554

On to step 3:
554 can be fit into 214 0 times, resulting in a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Fetch the next digit (0) from the dividend, attach it to 214 and continue: 2140 / 554

Going ahead to step 4:
554 goes into 2140 3 times with a remainder of 478.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1662 from 2140, we get 478.
Bring next digit (4) of the dividend behind the 478 and repeat the process: 4784 / 554

Advancing to step 5:
When dividing 4784 by 554, we get 8 with a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 4432 from 4784 to get 352.
Append the next digit (6) from the dividend to 352 and continue with: 3526 / 554

On to step 6:
If we divide 3526 by 554, we get 6 and a remainder of 202.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
Deduct 3324 from 3526 and we're left with 202.
Fetch the next digit (0) from the dividend, attach it to 202 and continue: 2020 / 554

Moving on to step 7:
When dividing 2020 by 554, we get 3 with a remainder of 358.
Write down 3 as next digit of the result. 
Result so far: 3863.0
Deduct 1662 from 2020 and we're left with 358.
Take the next digit (7) from the dividend and append it to 358, then repeat: 3587 / 554

Advancing to step 8:
When dividing 3587 by 554, we get 6 with a remainder of 263.
The next digit of our result is 6. 
Result so far: 38636.0
Subtracting 3324 from 3587 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
554 goes into 2630 4 times with a remainder of 414.
Write down 4 as next digit of the result. 
Result so far: 38636.4
Subtracting 2216 from 2630 leaves us 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.

On to step 10:
554 goes into 4140 7 times with a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 38636.47
Subtract 3878 from 4140 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 11:
554 can be fit into 2620 4 times, resulting in a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 38636.474
If we take 2216 away from 2620, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 12:
The number 554 fits into 4040 7 times, leaving a remainder of 162.
Use 7 as the next digit of our solution. 
Result so far: 38636.4747
The remainder is 162 after subtracting 3878 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 13:
When dividing 1620 by 554, we get 2 with a remainder of 512.
Record the quotient 2 as the next digit in the result. 
Result so far: 38636.47472
Subtract 1108 from 1620 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 14:
554 goes into 5120 9 times with a remainder of 134.
Write down 9 as next digit of the result. 
Result so far: 38636.474729
Deduct 4986 from 5120 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 15:
The number 554 fits into 1340 2 times, leaving a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 38636.4747292
If we subtract 1108 from 1340, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 16:
The number 554 fits into 2320 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 38636.47472924
If we take 2216 away from 2320, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 38636.47472924 with a remainder of 1.04e-07.
