54517906 ÷ 10 
We want to figure out the number of times 54517906 can be divided by 10.

On to step 1:
The number 10 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 10

Going ahead to step 2:
When dividing 54 by 10, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 50 from 54 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 10

On to step 3:
10 goes into 45 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 40 from 45 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 10

Step 4:
The number 10 fits into 51 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Deduct 50 from 51 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 10

Moving on to step 5:
If we divide 17 by 10, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 5451.0
Deduct 10 from 17 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 10

Advancing to step 6:
10 goes into 79 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 54517.0
Deduct 70 from 79 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 10

Moving on to step 7:
90 divided by 10 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 545179.0
Subtract 90 from 90 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 10

Step 8:
10 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 5451790.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
10 goes into 60 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5451790.6
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5451790.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5451790.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5451790.6, with a leftover of 0.0.
