We divide 421477 by 4
We're looking to find how many times 4 goes into 421477.

On to step 1:
4 can be fit into 4 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 4

Advancing to step 2:
2 divided by 4 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

Moving on to step 3:
4 can be fit into 21 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 20 from 21, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Moving on to step 4:
4 can be fit into 14 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1053.0
The remainder is 2 after subtracting 12 from 14.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 4

Let's proceed to step 5:
4 goes into 27 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 10536.0
If we subtract 24 from 27, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

Going ahead to step 6:
37 divided by 4 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 105369.0
Subtracting 36 from 37 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 105369.2
Subtracting 8 from 10 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 105369.25
Deduct 20 from 20 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.

On to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 105369.25
Subtracting 0 from 0 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.

Let's proceed to step 10:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 105369.25
If we take 0 away from 0, we end up 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 105369.25 and a remainder of 0.0.
