We divide 861945 by 23
We're looking to find how many times 23 goes into 861945.

Going ahead to step 1:
23 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 23

Moving on to step 2:
The number 23 fits into 86 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 69 from 86 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 23

Moving on to step 3:
23 can be fit into 171 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 161 from 171, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 23

Step 4:
23 goes into 109 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 374.0
The remainder is 17 after subtracting 92 from 109.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 23

Going ahead to step 5:
23 goes into 174 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3747.0
The remainder is 13 after subtracting 161 from 174.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 23

On to step 6:
If we divide 135 by 23, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 37475.0
Subtract 115 from 135 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 23 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 37475.8
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.

Moving on to step 8:
If we divide 160 by 23, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 37475.86
Subtract 138 from 160 to 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 9:
220 divided by 23 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 37475.869
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.

Step 10:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 37475.8695
Subtracting 115 from 130 leaves us 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.

Step 11:
150 divided by 23 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 37475.86956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
23 goes into 120 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 37475.869565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
50 divided by 23 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 37475.8695652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 37475.86956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 37475.86956521, with a leftover of 1.7e-08.
