Let's divide 51254628 by 9
We want to figure out the number of times 51254628 can be divided by 9.

Advancing to step 1:
The number 9 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 9

Let's proceed to step 2:
51 divided by 9 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 45 away from 51, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 9

Step 3:
62 divided by 9 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 54 from 62 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 9

Moving on to step 4:
9 can be fit into 85 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 569.0
If we subtract 81 from 85, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 9

On to step 5:
The number 9 fits into 44 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5694.0
Subtract 36 from 44 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 9

Step 6:
86 divided by 9 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 56949.0
If we take 81 away from 86, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 9

Let's proceed to step 7:
The number 9 fits into 52 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 569495.0
Subtract 45 from 52 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 9

Going ahead to step 8:
If we divide 78 by 9, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 5694958.0
Deduct 72 from 78 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 9, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 5694958.6
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
When dividing 60 by 9, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 5694958.66
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 5694958.66, with a leftover of 0.006.
