Let's divide 23915236 by 858
We want to figure out the number of times 23915236 can be divided by 858.

Advancing to step 1:
858 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 858

On to step 2:
When dividing 23 by 858, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 858

Advancing to step 3:
858 can be fit into 239 0 times, resulting in a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 239 leaves us with 239.
Grab the next digit (1) from the dividend, add it to 239, then carry on: 2391 / 858

Let's proceed to step 4:
858 goes into 2391 2 times with a remainder of 675.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1716 from 2391 to get 675.
Grab the next digit (5) from the dividend, add it to 675, then carry on: 6755 / 858

Advancing to step 5:
858 goes into 6755 7 times with a remainder of 749.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 6006 from 6755, we get 749.
Take the next digit (2) from the dividend and append it to 749, then repeat: 7492 / 858

Advancing to step 6:
7492 divided by 858 is 8 with a remainder of 628.
The next digit of our result is 8. 
Result so far: 278.0
Subtract 6864 from 7492 to get 628.
Append the next digit (3) from the dividend to 628 and continue with: 6283 / 858

Step 7:
858 goes into 6283 7 times with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 2787.0
Subtracting 6006 from 6283 leaves us with 277.
Bring next digit (6) of the dividend behind the 277 and repeat the process: 2776 / 858

Let's proceed to step 8:
If we divide 2776 by 858, we get 3 and a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 27873.0
Subtracting 2574 from 2776 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
858 goes into 2020 2 times with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 27873.2
The remainder is 304 after subtracting 1716 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 10:
858 goes into 3040 3 times with a remainder of 466.
Use 3 as the next digit of our solution. 
Result so far: 27873.23
Subtract 2574 from 3040 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 11:
858 goes into 4660 5 times with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 27873.235
Subtracting 4290 from 4660 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
If we divide 3700 by 858, we get 4 and a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 27873.2354
If we take 3432 away from 3700, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 13:
2680 divided by 858 is 3 with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 27873.23543
If we subtract 2574 from 2680, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 14:
858 can be fit into 1060 1 times, resulting in a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 27873.235431
If we take 858 away from 1060, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 15:
2020 divided by 858 is 2 with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 27873.2354312
Subtracting 1716 from 2020 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
When dividing 3040 by 858, we get 3 with a remainder of 466.
Write down 3 as next digit of the result. 
Result so far: 27873.23543123
Subtract 2574 from 3040 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

After the division, we end up with 27873.23543123 and a remainder of 4.66e-07.
