We look at the division of 861894 by 23 
We want to figure out the number of times 861894 can be divided by 23.

Let's proceed to step 1:
The number 23 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 23

Let's proceed to step 2:
The number 23 fits into 86 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 69 from 86, we get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 23

Step 3:
The number 23 fits into 171 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 161 away from 171, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 23

Let's proceed to step 4:
108 divided by 23 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 374.0
Deduct 92 from 108 and we're left with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 23

Going ahead to step 5:
The number 23 fits into 169 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 3747.0
Subtract 161 from 169 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 23

On to step 6:
The number 23 fits into 84 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 37473.0
If we subtract 69 from 84, we get 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 7:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 37473.6
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 37473.65
Deduct 115 from 120 and we're left 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.

Let's proceed to step 9:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 37473.652
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.

Moving on to step 10:
23 goes into 40 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 37473.6521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
170 divided by 23 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 37473.65217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 23, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 37473.652173
Subtracting 69 from 90 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 37473.6521739
If we take 207 away from 210, we end up 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.

Moving on to step 14:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 37473.65217391
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.

The final outcome is 37473.65217391, with a leftover of 7e-09.
