We look at the division of 1083340 by 858 
Our goal is to divide 1083340 by 858.

Advancing to step 1:
858 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 858

Let's proceed to step 2:
If we divide 10 by 858, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 858

Advancing to step 3:
108 divided by 858 is 0 with a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 108, we get 108.
Include the next digit (3) from the dividend after 108, then repeat: 1083 / 858

Let's proceed to step 4:
If we divide 1083 by 858, we get 1 and a remainder of 225.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 858 from 1083 to get 225.
Include the next digit (3) from the dividend after 225, then repeat: 2253 / 858

Advancing to step 5:
858 can be fit into 2253 2 times, resulting in a remainder of 537.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1716 from 2253 and we're left with 537.
Fetch the next digit (4) from the dividend, attach it to 537 and continue: 5374 / 858

Advancing to step 6:
858 goes into 5374 6 times with a remainder of 226.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 5148 from 5374 leaves us with 226.
Bring next digit (0) of the dividend behind the 226 and repeat the process: 2260 / 858

Advancing to step 7:
858 goes into 2260 2 times with a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 1262.0
Subtract 1716 from 2260 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 8:
If we divide 5440 by 858, we get 6 and a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 1262.6
If we take 5148 away from 5440, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
2920 divided by 858 is 3 with a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 1262.63
Deduct 2574 from 2920 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 10:
If we divide 3460 by 858, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1262.634
If we subtract 3432 from 3460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
858 goes into 280 0 times with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 1262.634
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
When dividing 2800 by 858, we get 3 with a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 1262.63403
The remainder is 226 after subtracting 2574 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 13:
858 can be fit into 2260 2 times, resulting in a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 1262.634032
Deduct 1716 from 2260 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 14:
5440 divided by 858 is 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 1262.6340326
Deduct 5148 from 5440 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 15:
858 goes into 2920 3 times with a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 1262.63403263
The remainder is 346 after subtracting 2574 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

The final outcome is 1262.63403263, with a leftover of 3.46e-07.
