420446 divided by 45 
We're looking to find how many times 45 goes into 420446.

Let's proceed to step 1:
45 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 45

Let's proceed to step 2:
45 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 45

Advancing to step 3:
If we divide 420 by 45, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 405 from 420 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 45

Moving on to step 4:
45 can be fit into 154 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 19 after subtracting 135 from 154.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 45

Moving on to step 5:
The number 45 fits into 194 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 934.0
The remainder is 14 after subtracting 180 from 194.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 45

Let's proceed to step 6:
45 goes into 146 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9343.0
If we subtract 135 from 146, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 45 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 9343.2
If we subtract 90 from 110, 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.

On to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9343.24
If we take 180 away from 200, we end up 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.

Advancing to step 9:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 9343.244
If we take 180 away from 200, we end up 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.

Our division results in 9343.244 with a remaining 0.002.
