We divide 1123004 by 858
We want to divide 1123004 by 858.

Advancing to step 1:
If we divide 1 by 858, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 858

Going ahead to step 2:
When dividing 11 by 858, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 858

Advancing to step 3:
When dividing 112 by 858, we get 0 with a remainder of 112.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 112, we get 112.
Include the next digit (3) from the dividend after 112, then repeat: 1123 / 858

Let's proceed to step 4:
858 goes into 1123 1 times with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 858 from 1123 to get 265.
Bring next digit (0) of the dividend behind the 265 and repeat the process: 2650 / 858

Advancing to step 5:
If we divide 2650 by 858, we get 3 and a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 2574 from 2650 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 858

Moving on to step 6:
When dividing 760 by 858, we get 0 with a remainder of 760.
The next digit of our result is 0. 
Result so far: 130.0
Deduct 0 from 760 and we're left with 760.
Grab the next digit (4) from the dividend, add it to 760, then carry on: 7604 / 858

Advancing to step 7:
858 goes into 7604 8 times with a remainder of 740.
Record the quotient 8 as the next digit in the result. 
Result so far: 1308.0
Subtract 6864 from 7604 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 8:
858 goes into 7400 8 times with a remainder of 536.
Write down 8 as next digit of the result. 
Result so far: 1308.8
Deduct 6864 from 7400 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 9:
858 can be fit into 5360 6 times, resulting in a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 1308.86
If we subtract 5148 from 5360, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
The number 858 fits into 2120 2 times, leaving a remainder of 404.
Use 2 as the next digit of our solution. 
Result so far: 1308.862
The remainder is 404 after subtracting 1716 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
The number 858 fits into 4040 4 times, leaving a remainder of 608.
The next digit of our result is 4. 
Result so far: 1308.8624
If we subtract 3432 from 4040, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 12:
The number 858 fits into 6080 7 times, leaving a remainder of 74.
The next digit of our result is 7. 
Result so far: 1308.86247
If we subtract 6006 from 6080, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
The number 858 fits into 740 0 times, leaving a remainder of 740.
The number 0 becomes the next digit in our result. 
Result so far: 1308.86247
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 14:
The number 858 fits into 7400 8 times, leaving a remainder of 536.
The next digit of our result is 8. 
Result so far: 1308.8624708
Subtract 6864 from 7400 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 15:
858 can be fit into 5360 6 times, resulting in a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 1308.86247086
Subtracting 5148 from 5360 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 1308.86247086 with a remainder of 2.12e-07.
