We look at the division of 902178 by 23 
Our goal is to divide 902178 by 23.

Advancing to step 1:
9 divided by 23 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 23

Going ahead to step 2:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 69 from 90, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 23

Step 3:
212 divided by 23 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 207 from 212 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 23

Let's proceed to step 4:
If we divide 51 by 23, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 392.0
Subtract 46 from 51 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 23

Step 5:
When dividing 57 by 23, we get 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 3922.0
Deduct 46 from 57 and we're left with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 23

Let's proceed to step 6:
118 divided by 23 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 39225.0
Subtracting 115 from 118 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 39225.1
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 39225.13
If we subtract 69 from 70, we get 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 9:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 39225.13
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 39225.1304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 39225.13043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 39225.130434
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
180 divided by 23 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 39225.1304347
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 39225.13043478
Subtract 184 from 190 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.

The quotient of the division is 39225.13043478, and the remainder is 6e-09.
