We look at the division of 20234047 by 858 
Let's see how many times 858 fits into 20234047.

Moving on to step 1:
858 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 858

On to step 2:
858 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 858

Step 3:
If we divide 202 by 858, we get 0 and a remainder of 202.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 202, we end up with 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 858

Advancing to step 4:
When dividing 2023 by 858, we get 2 with a remainder of 307.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1716 from 2023 and we're left with 307.
Fetch the next digit (4) from the dividend, attach it to 307 and continue: 3074 / 858

Moving on to step 5:
If we divide 3074 by 858, we get 3 and a remainder of 500.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 2574 from 3074 leaves us with 500.
Append the next digit (0) from the dividend to 500 and continue with: 5000 / 858

Advancing to step 6:
The number 858 fits into 5000 5 times, leaving a remainder of 710.
Write down 5 as next digit of the result. 
Result so far: 235.0
If we subtract 4290 from 5000, we get 710.
Append the next digit (4) from the dividend to 710 and continue with: 7104 / 858

On to step 7:
When dividing 7104 by 858, we get 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 2358.0
If we subtract 6864 from 7104, we get 240.
Fetch the next digit (7) from the dividend, attach it to 240 and continue: 2407 / 858

Step 8:
2407 divided by 858 is 2 with a remainder of 691.
The number 2 becomes the next digit in our result. 
Result so far: 23582.0
The remainder is 691 after subtracting 1716 from 2407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 9:
If we divide 6910 by 858, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 23582.8
Subtract 6864 from 6910 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 858 is 0 with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 23582.8
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
The number 858 fits into 4600 5 times, leaving a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 23582.805
Deduct 4290 from 4600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 12:
The number 858 fits into 3100 3 times, leaving a remainder of 526.
Record the quotient 3 as the next digit in the result. 
Result so far: 23582.8053
Subtracting 2574 from 3100 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 13:
5260 divided by 858 is 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 23582.80536
Deduct 5148 from 5260 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 14:
858 goes into 1120 1 times with a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 23582.805361
If we subtract 858 from 1120, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 15:
2620 divided by 858 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 23582.8053613
Deduct 2574 from 2620 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 16:
The number 858 fits into 460 0 times, leaving a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 23582.8053613
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 23582.8053613 with a remainder of 4.6e-07.
