Let's divide 90331886 by 408
We want to figure out the number of times 90331886 can be divided by 408.

On to step 1:
When dividing 9 by 408, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 408

Moving on to step 2:
The number 408 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 408

Moving on to step 3:
408 can be fit into 903 2 times, resulting in a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 816 away from 903, we end up with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 408

Moving on to step 4:
408 can be fit into 873 2 times, resulting in a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 816 from 873 leaves us with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 408

Moving on to step 5:
408 can be fit into 571 1 times, resulting in a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
Subtract 408 from 571 to get 163.
Fetch the next digit (8) from the dividend, attach it to 163 and continue: 1638 / 408

Moving on to step 6:
When dividing 1638 by 408, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2214.0
The remainder is 6 after subtracting 1632 from 1638.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 408

Moving on to step 7:
68 divided by 408 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 22140.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 408

Let's proceed to step 8:
408 goes into 686 1 times with a remainder of 278.
The next digit of our result is 1. 
Result so far: 221401.0
If we take 408 away from 686, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 9:
If we divide 2780 by 408, we get 6 and a remainder of 332.
Record the quotient 6 as the next digit in the result. 
Result so far: 221401.6
If we take 2448 away from 2780, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
3320 divided by 408 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 221401.68
The remainder is 56 after subtracting 3264 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
408 can be fit into 560 1 times, resulting in a remainder of 152.
The next digit of our result is 1. 
Result so far: 221401.681
Subtracting 408 from 560 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
If we divide 1520 by 408, we get 3 and a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 221401.6813
The remainder is 296 after subtracting 1224 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 13:
408 goes into 2960 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 221401.68137
The remainder is 104 after subtracting 2856 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 14:
The number 408 fits into 1040 2 times, leaving a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 221401.681372
The remainder is 224 after subtracting 816 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 15:
The number 408 fits into 2240 5 times, leaving a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 221401.6813725
Deduct 2040 from 2240 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.

Step 16:
2000 divided by 408 is 4 with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 221401.68137254
The remainder is 368 after subtracting 1632 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 221401.68137254 with a remaining 3.68e-07.
