We're looking to find how many times 478 goes into 91423420.

On to step 1:
478 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 478

Going ahead to step 2:
91 divided by 478 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (4) from the dividend, attach it to 91 and continue: 914 / 478

Moving on to step 3:
If we divide 914 by 478, we get 1 and a remainder of 436.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 436 after subtracting 478 from 914.
Fetch the next digit (2) from the dividend, attach it to 436 and continue: 4362 / 478

Moving on to step 4:
478 goes into 4362 9 times with a remainder of 60.
The next digit of our result is 9. 
Result so far: 19.0
If we take 4302 away from 4362, we end up with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 478

Moving on to step 5:
478 can be fit into 603 1 times, resulting in a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 191.0
If we take 478 away from 603, we end up with 125.
Fetch the next digit (4) from the dividend, attach it to 125 and continue: 1254 / 478

Let's proceed to step 6:
478 can be fit into 1254 2 times, resulting in a remainder of 298.
Write down 2 as next digit of the result. 
Result so far: 1912.0
The remainder is 298 after subtracting 956 from 1254.
Append the next digit (2) from the dividend to 298 and continue with: 2982 / 478

Step 7:
478 can be fit into 2982 6 times, resulting in a remainder of 114.
The next digit of our result is 6. 
Result so far: 19126.0
Subtract 2868 from 2982 to get 114.
Take the next digit (0) from the dividend and append it to 114, then repeat: 1140 / 478

On to step 8:
478 goes into 1140 2 times with a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 191262.0
Subtract 956 from 1140 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
If we divide 1840 by 478, we get 3 and a remainder of 406.
Write down 3 as next digit of the result. 
Result so far: 191262.3
Subtract 1434 from 1840 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 10:
4060 divided by 478 is 8 with a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 191262.38
Subtracting 3824 from 4060 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 11:
478 can be fit into 2360 4 times, resulting in a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 191262.384
If we subtract 1912 from 2360, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 12:
4480 divided by 478 is 9 with a remainder of 178.
Use 9 as the next digit of our solution. 
Result so far: 191262.3849
The remainder is 178 after subtracting 4302 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 13:
The number 478 fits into 1780 3 times, leaving a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 191262.38493
Deduct 1434 from 1780 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 14:
3460 divided by 478 is 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 191262.384937
Subtract 3346 from 3460 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 15:
478 goes into 1140 2 times with a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 191262.3849372
If we take 956 away from 1140, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 16:
If we divide 1840 by 478, we get 3 and a remainder of 406.
The next digit of our result is 3. 
Result so far: 191262.38493723
Subtracting 1434 from 1840 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

In conclusion, the division gives 191262.38493723 with a balance of 4.06e-07.
