We look at the division of 4861503 by 858 
We want to divide 4861503 by 858.

Going ahead to step 1:
If we divide 4 by 858, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 858

Advancing to step 2:
858 can be fit into 48 0 times, resulting in a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 858

Moving on to step 3:
When dividing 486 by 858, we get 0 with a remainder of 486.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 486, we get 486.
Grab the next digit (1) from the dividend, add it to 486, then carry on: 4861 / 858

Advancing to step 4:
4861 divided by 858 is 5 with a remainder of 571.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 571 after subtracting 4290 from 4861.
Include the next digit (5) from the dividend after 571, then repeat: 5715 / 858

On to step 5:
5715 divided by 858 is 6 with a remainder of 567.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 5148 from 5715 and we're left with 567.
Fetch the next digit (0) from the dividend, attach it to 567 and continue: 5670 / 858

Moving on to step 6:
5670 divided by 858 is 6 with a remainder of 522.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
If we subtract 5148 from 5670, we get 522.
Grab the next digit (3) from the dividend, add it to 522, then carry on: 5223 / 858

Step 7:
If we divide 5223 by 858, we get 6 and a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 5666.0
Subtract 5148 from 5223 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
750 divided by 858 is 0 with a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 5666.0
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 9:
When dividing 7500 by 858, we get 8 with a remainder of 636.
Put 8 as the next digit of the answer. 
Result so far: 5666.08
If we subtract 6864 from 7500, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
858 goes into 6360 7 times with a remainder of 354.
Record the quotient 7 as the next digit in the result. 
Result so far: 5666.087
The remainder is 354 after subtracting 6006 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 11:
3540 divided by 858 is 4 with a remainder of 108.
The next digit of our result is 4. 
Result so far: 5666.0874
The remainder is 108 after subtracting 3432 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 12:
If we divide 1080 by 858, we get 1 and a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 5666.08741
If we take 858 away from 1080, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 13:
If we divide 2220 by 858, we get 2 and a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 5666.087412
Subtract 1716 from 2220 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 14:
The number 858 fits into 5040 5 times, leaving a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 5666.0874125
Deduct 4290 from 5040 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 15:
The number 858 fits into 7500 8 times, leaving a remainder of 636.
The next digit of our result is 8. 
Result so far: 5666.08741258
Deduct 6864 from 7500 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final result is 5666.08741258 with a remainder of 6.36e-07.
