We divide 40504466 by 420
We want to figure out the number of times 40504466 can be divided by 420.

Step 1:
4 divided by 420 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 420

Advancing to step 2:
When dividing 40 by 420, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 420

Step 3:
The number 420 fits into 405 0 times, leaving a remainder of 405.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 405 after subtracting 0 from 405.
Append the next digit (0) from the dividend to 405 and continue with: 4050 / 420

On to step 4:
If we divide 4050 by 420, we get 9 and a remainder of 270.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 3780 away from 4050, we end up with 270.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 420

Advancing to step 5:
420 can be fit into 2704 6 times, resulting in a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 184 after subtracting 2520 from 2704.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 420

On to step 6:
If we divide 1844 by 420, we get 4 and a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 964.0
If we subtract 1680 from 1844, we get 164.
Fetch the next digit (6) from the dividend, attach it to 164 and continue: 1646 / 420

Moving on to step 7:
420 goes into 1646 3 times with a remainder of 386.
Use 3 as the next digit of our solution. 
Result so far: 9643.0
If we subtract 1260 from 1646, we get 386.
Include the next digit (6) from the dividend after 386, then repeat: 3866 / 420

Let's proceed to step 8:
When dividing 3866 by 420, we get 9 with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 96439.0
If we take 3780 away from 3866, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
The number 420 fits into 860 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 96439.2
Deduct 840 from 860 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.

Step 10:
When dividing 200 by 420, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 96439.2
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
The next digit of our result is 4. 
Result so far: 96439.204
The remainder is 320 after subtracting 1680 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
3200 divided by 420 is 7 with a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 96439.2047
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
420 can be fit into 2600 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 96439.20476
Subtracting 2520 from 2600 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
420 can be fit into 800 1 times, resulting in a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 96439.204761
If we take 420 away from 800, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
When dividing 3800 by 420, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 96439.2047619
Subtracting 3780 from 3800 leaves us 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.

On to step 16:
420 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 96439.2047619
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 96439.2047619 and a remainder of 2e-07.
