551597 divided by 45 
We want to figure out the number of times 551597 can be divided by 45.

Advancing to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 45

Advancing to step 2:
The number 45 fits into 55 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 55 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 45

Let's proceed to step 3:
If we divide 101 by 45, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 90 from 101 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 45

Step 4:
The number 45 fits into 115 2 times, leaving a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Deduct 90 from 115 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 45

Step 5:
259 divided by 45 is 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 1225.0
If we subtract 225 from 259, we get 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 45

Let's proceed to step 6:
45 goes into 347 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 12257.0
If we take 315 away from 347, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
45 can be fit into 320 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 12257.7
Subtracting 315 from 320 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 12257.71
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 45, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 12257.711
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 12257.711, with a leftover of 0.0005.
