21921542 divided by 551 
We're looking to find how many times 551 goes into 21921542.

On to step 1:
2 divided by 551 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 551

On to step 2:
551 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 551

Moving on to step 3:
If we divide 219 by 551, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Append the next digit (2) from the dividend to 219 and continue with: 2192 / 551

Going ahead to step 4:
551 goes into 2192 3 times with a remainder of 539.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1653 from 2192 to get 539.
Bring next digit (1) of the dividend behind the 539 and repeat the process: 5391 / 551

Moving on to step 5:
If we divide 5391 by 551, we get 9 and a remainder of 432.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 4959 from 5391, we get 432.
Append the next digit (5) from the dividend to 432 and continue with: 4325 / 551

Moving on to step 6:
When dividing 4325 by 551, we get 7 with a remainder of 468.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtract 3857 from 4325 to get 468.
Take the next digit (4) from the dividend and append it to 468, then repeat: 4684 / 551

Let's proceed to step 7:
551 goes into 4684 8 times with a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 3978.0
If we subtract 4408 from 4684, we get 276.
Fetch the next digit (2) from the dividend, attach it to 276 and continue: 2762 / 551

On to step 8:
551 goes into 2762 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 39785.0
Subtracting 2755 from 2762 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
551 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 39785.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
The number 551 fits into 700 1 times, leaving a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 39785.01
If we take 551 away from 700, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 11:
1490 divided by 551 is 2 with a remainder of 388.
The next digit of our result is 2. 
Result so far: 39785.012
If we take 1102 away from 1490, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 12:
If we divide 3880 by 551, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 39785.0127
If we subtract 3857 from 3880, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
551 can be fit into 230 0 times, resulting in a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 39785.0127
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 14:
The number 551 fits into 2300 4 times, leaving a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 39785.012704
If we subtract 2204 from 2300, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
551 can be fit into 960 1 times, resulting in a remainder of 409.
Record the quotient 1 as the next digit in the result. 
Result so far: 39785.0127041
Deduct 551 from 960 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 16:
551 can be fit into 4090 7 times, resulting in a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 39785.01270417
Deduct 3857 from 4090 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

In conclusion, the division gives 39785.01270417 with a balance of 2.33e-07.
