We're dividing 90638078 by 406 
Let's see how many times 406 fits into 90638078.

Let's proceed to step 1:
9 divided by 406 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 406

Step 2:
When dividing 90 by 406, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 406

Moving on to step 3:
The number 406 fits into 906 2 times, leaving a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 94 after subtracting 812 from 906.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 406

Let's proceed to step 4:
When dividing 943 by 406, we get 2 with a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 131 after subtracting 812 from 943.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 406

Step 5:
1318 divided by 406 is 3 with a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Subtracting 1218 from 1318 leaves us with 100.
Fetch the next digit (0) from the dividend, attach it to 100 and continue: 1000 / 406

Step 6:
If we divide 1000 by 406, we get 2 and a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 2232.0
The remainder is 188 after subtracting 812 from 1000.
Bring next digit (7) of the dividend behind the 188 and repeat the process: 1887 / 406

Let's proceed to step 7:
406 goes into 1887 4 times with a remainder of 263.
The next digit of our result is 4. 
Result so far: 22324.0
Subtract 1624 from 1887 to get 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 406

Going ahead to step 8:
2638 divided by 406 is 6 with a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 223246.0
Subtract 2436 from 2638 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 9:
When dividing 2020 by 406, we get 4 with a remainder of 396.
The next digit of our result is 4. 
Result so far: 223246.4
Subtract 1624 from 2020 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 10:
3960 divided by 406 is 9 with a remainder of 306.
The next digit of our result is 9. 
Result so far: 223246.49
The remainder is 306 after subtracting 3654 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
The number 406 fits into 3060 7 times, leaving a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 223246.497
The remainder is 218 after subtracting 2842 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
When dividing 2180 by 406, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 223246.4975
Subtract 2030 from 2180 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
406 goes into 1500 3 times with a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 223246.49753
Deduct 1218 from 1500 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 14:
406 goes into 2820 6 times with a remainder of 384.
The next digit of our result is 6. 
Result so far: 223246.497536
Deduct 2436 from 2820 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 15:
When dividing 3840 by 406, we get 9 with a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 223246.4975369
The remainder is 186 after subtracting 3654 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 16:
406 can be fit into 1860 4 times, resulting in a remainder of 236.
The next digit of our result is 4. 
Result so far: 223246.49753694
If we take 1624 away from 1860, we end up 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.

The final outcome is 223246.49753694, with a leftover of 2.36e-07.
