We look at the division of 90806214 by 23 
We want to figure out the number of times 90806214 can be divided by 23.

Let's proceed to step 1:
The number 23 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 23

Let's proceed to step 2:
When dividing 90 by 23, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 21 after subtracting 69 from 90.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 23

Step 3:
218 divided by 23 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 207 from 218, we get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 23

Advancing to step 4:
If we divide 110 by 23, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
Deduct 92 from 110 and we're left with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 23

Going ahead to step 5:
The number 23 fits into 186 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 3948.0
Deduct 184 from 186 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 23

Let's proceed to step 6:
If we divide 22 by 23, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 39480.0
If we take 0 away from 22, we end up with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 23

Going ahead to step 7:
The number 23 fits into 221 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 394809.0
Deduct 207 from 221 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 23

Going ahead to step 8:
The number 23 fits into 144 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3948096.0
Subtract 138 from 144 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
23 goes into 60 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 3948096.2
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
23 goes into 140 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 3948096.26
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
20 divided by 23 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3948096.26
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
200 divided by 23 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 3948096.2608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
23 goes into 160 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 3948096.26086
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 3948096.260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 15:
130 divided by 23 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3948096.2608695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3948096.26086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3948096.26086956, and the remainder is 1.2e-08.
