Let's divide 213561 by 23
Let's see how many times 23 fits into 213561.

Step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Going ahead to step 2:
If we divide 21 by 23, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 23

Advancing to step 3:
When dividing 213 by 23, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 207 from 213 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 23

Step 4:
When dividing 65 by 23, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we take 46 away from 65, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 23

Going ahead to step 5:
When dividing 196 by 23, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 928.0
Subtracting 184 from 196 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 23

Let's proceed to step 6:
23 can be fit into 121 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 9285.0
If we take 115 away from 121, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 23, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 9285.2
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9285.26
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 23, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9285.26
Deduct 0 from 20 and we're left with 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 10:
If we divide 200 by 23, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9285.2608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 9285.26086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
23 goes into 220 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 9285.260869
If we take 207 away from 220, we end up 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.

Step 13:
When dividing 130 by 23, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9285.2608695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9285.26086956
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 final result is 9285.26086956 with a remainder of 1.2e-08.
