857971 ÷ 24 
We're looking to find how many times 24 goes into 857971.

On to step 1:
8 divided by 24 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 24

Step 2:
When dividing 85 by 24, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 72 from 85 leaves us with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 24

Step 3:
24 goes into 137 5 times with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 120 from 137 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 24

On to step 4:
When dividing 179 by 24, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 357.0
The remainder is 11 after subtracting 168 from 179.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 24

On to step 5:
If we divide 117 by 24, we get 4 and a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 3574.0
Deduct 96 from 117 and we're left with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 24

On to step 6:
24 can be fit into 211 8 times, resulting in a remainder of 19.
The next digit of our result is 8. 
Result so far: 35748.0
If we subtract 192 from 211, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 24, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 35748.7
If we take 168 away from 190, 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.

Step 8:
When dividing 220 by 24, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 35748.79
Subtracting 216 from 220 leaves us 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.

Step 9:
The number 24 fits into 40 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 35748.791
Deduct 24 from 40 and we're left 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.

Going ahead to step 10:
24 goes into 160 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 35748.7916
If we subtract 144 from 160, we 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.

Step 11:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 35748.79166
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 35748.79166 with a remainder of 1.6e-05.
