We're dividing 7273146 by 858 
Our goal is to divide 7273146 by 858.

Step 1:
If we divide 7 by 858, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 858

Step 2:
858 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 858

Let's proceed to step 3:
858 can be fit into 727 0 times, resulting in a remainder of 727.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 727 to get 727.
Bring next digit (3) of the dividend behind the 727 and repeat the process: 7273 / 858

Step 4:
If we divide 7273 by 858, we get 8 and a remainder of 409.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6864 from 7273 to get 409.
Take the next digit (1) from the dividend and append it to 409, then repeat: 4091 / 858

Step 5:
If we divide 4091 by 858, we get 4 and a remainder of 659.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 3432 from 4091 to get 659.
Fetch the next digit (4) from the dividend, attach it to 659 and continue: 6594 / 858

Moving on to step 6:
858 can be fit into 6594 7 times, resulting in a remainder of 588.
The next digit of our result is 7. 
Result so far: 847.0
The remainder is 588 after subtracting 6006 from 6594.
Include the next digit (6) from the dividend after 588, then repeat: 5886 / 858

Advancing to step 7:
858 goes into 5886 6 times with a remainder of 738.
The number 6 becomes the next digit in our result. 
Result so far: 8476.0
If we take 5148 away from 5886, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Advancing to step 8:
858 can be fit into 7380 8 times, resulting in a remainder of 516.
The number 8 becomes the next digit in our result. 
Result so far: 8476.8
The remainder is 516 after subtracting 6864 from 7380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 9:
858 can be fit into 5160 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8476.86
If we subtract 5148 from 5160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
858 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 8476.86
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
When dividing 1200 by 858, we get 1 with a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 8476.8601
Subtract 858 from 1200 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 12:
858 goes into 3420 3 times with a remainder of 846.
Write down 3 as next digit of the result. 
Result so far: 8476.86013
Subtracting 2574 from 3420 leaves us with 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Step 13:
When dividing 8460 by 858, we get 9 with a remainder of 738.
Record the quotient 9 as the next digit in the result. 
Result so far: 8476.860139
Deduct 7722 from 8460 and we're left with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Going ahead to step 14:
858 goes into 7380 8 times with a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 8476.8601398
The remainder is 516 after subtracting 6864 from 7380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 15:
When dividing 5160 by 858, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 8476.86013986
Deduct 5148 from 5160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8476.86013986 with a remaining 1.2e-08.
