We look at the division of 76003513 by 858 
We're looking to find how many times 858 goes into 76003513.

Going ahead to step 1:
The number 858 fits into 7 0 times, leaving 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.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 858

Going ahead to step 2:
When dividing 76 by 858, we get 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 858

Moving on to step 3:
When dividing 760 by 858, we get 0 with a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 760 to get 760.
Grab the next digit (0) from the dividend, add it to 760, then carry on: 7600 / 858

Going ahead to step 4:
858 goes into 7600 8 times with a remainder of 736.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6864 from 7600 and we're left with 736.
Append the next digit (3) from the dividend to 736 and continue with: 7363 / 858

On to step 5:
7363 divided by 858 is 8 with a remainder of 499.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Deduct 6864 from 7363 and we're left with 499.
Include the next digit (5) from the dividend after 499, then repeat: 4995 / 858

On to step 6:
If we divide 4995 by 858, we get 5 and a remainder of 705.
Write down 5 as next digit of the result. 
Result so far: 885.0
Subtracting 4290 from 4995 leaves us with 705.
Include the next digit (1) from the dividend after 705, then repeat: 7051 / 858

On to step 7:
858 goes into 7051 8 times with a remainder of 187.
Use 8 as the next digit of our solution. 
Result so far: 8858.0
If we subtract 6864 from 7051, we get 187.
Bring next digit (3) of the dividend behind the 187 and repeat the process: 1873 / 858

Going ahead to step 8:
858 goes into 1873 2 times with a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 88582.0
Deduct 1716 from 1873 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
When dividing 1570 by 858, we get 1 with a remainder of 712.
The next digit of our result is 1. 
Result so far: 88582.1
Deduct 858 from 1570 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 10:
The number 858 fits into 7120 8 times, leaving a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 88582.18
If we take 6864 away from 7120, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
The number 858 fits into 2560 2 times, leaving a remainder of 844.
Put 2 as the next digit of the answer. 
Result so far: 88582.182
If we subtract 1716 from 2560, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Let's proceed to step 12:
858 goes into 8440 9 times with a remainder of 718.
Record the quotient 9 as the next digit in the result. 
Result so far: 88582.1829
The remainder is 718 after subtracting 7722 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 13:
The number 858 fits into 7180 8 times, leaving a remainder of 316.
The next digit of our result is 8. 
Result so far: 88582.18298
Subtract 6864 from 7180 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
858 goes into 3160 3 times with a remainder of 586.
Record the quotient 3 as the next digit in the result. 
Result so far: 88582.182983
Deduct 2574 from 3160 and we're left with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Moving on to step 15:
858 can be fit into 5860 6 times, resulting in a remainder of 712.
Put 6 as the next digit of the answer. 
Result so far: 88582.1829836
If we take 5148 away from 5860, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 16:
The number 858 fits into 7120 8 times, leaving a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 88582.18298368
If we subtract 6864 from 7120, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 88582.18298368 with a balance of 2.56e-07.
