We divide 420516 by 45
We're looking to find how many times 45 goes into 420516.

Advancing to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 45

Advancing to step 2:
When dividing 42 by 45, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 45

Advancing to step 3:
45 can be fit into 420 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 15 after subtracting 405 from 420.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 45

Going ahead to step 4:
45 can be fit into 155 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we take 135 away from 155, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 45

Advancing to step 5:
When dividing 201 by 45, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 934.0
The remainder is 21 after subtracting 180 from 201.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 45

Going ahead to step 6:
When dividing 216 by 45, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9344.0
If we subtract 180 from 216, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 45, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 9344.8
Subtracting 360 from 360 leaves us 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.

Step 8:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9344.8
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.

Step 9:
45 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9344.8
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.

After the division, we end up with 9344.8 and a remainder of 0.0.
