We look at the division of 30426531 by 551 
Let's see how many times 551 fits into 30426531.

Step 1:
If we divide 3 by 551, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 551

Step 2:
551 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 551

On to step 3:
304 divided by 551 is 0 with a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 304 to get 304.
Fetch the next digit (2) from the dividend, attach it to 304 and continue: 3042 / 551

Moving on to step 4:
The number 551 fits into 3042 5 times, leaving a remainder of 287.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 2755 away from 3042, we end up with 287.
Append the next digit (6) from the dividend to 287 and continue with: 2876 / 551

Moving on to step 5:
If we divide 2876 by 551, we get 5 and a remainder of 121.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 121 after subtracting 2755 from 2876.
Include the next digit (5) from the dividend after 121, then repeat: 1215 / 551

Advancing to step 6:
551 goes into 1215 2 times with a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 552.0
The remainder is 113 after subtracting 1102 from 1215.
Include the next digit (3) from the dividend after 113, then repeat: 1133 / 551

Step 7:
The number 551 fits into 1133 2 times, leaving a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 5522.0
The remainder is 31 after subtracting 1102 from 1133.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 551

Step 8:
551 goes into 311 0 times with a remainder of 311.
Write down 0 as next digit of the result. 
Result so far: 55220.0
Deduct 0 from 311 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 9:
If we divide 3110 by 551, we get 5 and a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 55220.5
If we subtract 2755 from 3110, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 10:
3550 divided by 551 is 6 with a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 55220.56
Deduct 3306 from 3550 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
551 can be fit into 2440 4 times, resulting in a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 55220.564
Deduct 2204 from 2440 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 12:
551 can be fit into 2360 4 times, resulting in a remainder of 156.
The next digit of our result is 4. 
Result so far: 55220.5644
If we subtract 2204 from 2360, 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.

The final outcome is 55220.5644, with a leftover of 0.00156.
