21759103 ÷ 551 
We want to figure out the number of times 21759103 can be divided by 551.

Going ahead to step 1:
551 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 551

Advancing to step 2:
21 divided by 551 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 551

Going ahead to step 3:
551 goes into 217 0 times with a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Take the next digit (5) from the dividend and append it to 217, then repeat: 2175 / 551

On to step 4:
When dividing 2175 by 551, we get 3 with a remainder of 522.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1653 away from 2175, we end up with 522.
Take the next digit (9) from the dividend and append it to 522, then repeat: 5229 / 551

Step 5:
551 goes into 5229 9 times with a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 4959 from 5229 and we're left with 270.
Append the next digit (1) from the dividend to 270 and continue with: 2701 / 551

On to step 6:
The number 551 fits into 2701 4 times, leaving a remainder of 497.
Write down 4 as next digit of the result. 
Result so far: 394.0
The remainder is 497 after subtracting 2204 from 2701.
Take the next digit (0) from the dividend and append it to 497, then repeat: 4970 / 551

On to step 7:
551 can be fit into 4970 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3949.0
Subtracting 4959 from 4970 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 551

Let's proceed to step 8:
When dividing 113 by 551, we get 0 with a remainder of 113.
The next digit of our result is 0. 
Result so far: 39490.0
Subtract 0 from 113 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
If we divide 1130 by 551, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 39490.2
Subtracting 1102 from 1130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 551, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 39490.2
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
If we divide 2800 by 551, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 39490.205
Subtract 2755 from 2800 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
551 can be fit into 450 0 times, resulting in a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 39490.205
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 13:
When dividing 4500 by 551, we get 8 with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 39490.20508
Deduct 4408 from 4500 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
551 can be fit into 920 1 times, resulting in a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 39490.205081
If we take 551 away from 920, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 15:
If we divide 3690 by 551, we get 6 and a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 39490.2050816
The remainder is 384 after subtracting 3306 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 16:
3840 divided by 551 is 6 with a remainder of 534.
Write down 6 as next digit of the result. 
Result so far: 39490.20508166
The remainder is 534 after subtracting 3306 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

In conclusion, the division gives 39490.20508166 with a balance of 5.34e-07.
