307861 ÷ 23 
We're looking to find how many times 23 goes into 307861.

Step 1:
3 divided by 23 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 23

Step 2:
30 divided by 23 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 23 from 30 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 23

Advancing to step 3:
The number 23 fits into 77 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 8 after subtracting 69 from 77.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 23

Moving on to step 4:
If we divide 88 by 23, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we take 69 away from 88, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 23

On to step 5:
23 goes into 196 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1338.0
Subtract 184 from 196 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 23

On to step 6:
When dividing 121 by 23, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 13385.0
Subtract 115 from 121 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.

Step 7:
23 goes into 60 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 13385.2
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
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: 13385.26
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.

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: 13385.26
Subtracting 0 from 20 leaves us 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:
23 goes into 200 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 13385.2608
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.

Going ahead to step 11:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 13385.26086
If we take 138 away from 160, we end up 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.

Advancing to step 12:
When dividing 220 by 23, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13385.260869
Deduct 207 from 220 and we're left 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.

Going ahead to step 13:
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: 13385.2608695
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.

Going ahead to step 14:
23 goes into 150 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 13385.26086956
Deduct 138 from 150 and we're left 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.

The final outcome is 13385.26086956, with a leftover of 1.2e-08.
