521417 divided by 45 
We want to figure out the number of times 521417 can be divided by 45.

Let's proceed to step 1:
The number 45 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.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 45

Let's proceed to step 2:
45 goes into 52 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 45 from 52.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 45

Let's proceed to step 3:
71 divided by 45 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 45 from 71 and we're left with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 45

Going ahead to step 4:
45 can be fit into 264 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 225 from 264, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 45

On to step 5:
45 goes into 391 8 times with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 1158.0
If we take 360 away from 391, we end up with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 45

Going ahead to step 6:
45 goes into 317 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 11587.0
Subtract 315 from 317 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 45, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11587.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11587.04
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 11587.044
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 11587.044 and a remainder of 0.002.
