71076589 ÷ 858 
Let's see how many times 858 fits into 71076589.

On to step 1:
858 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 858

Let's proceed to step 2:
If we divide 71 by 858, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 858

Advancing to step 3:
710 divided by 858 is 0 with a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 710 after subtracting 0 from 710.
Include the next digit (7) from the dividend after 710, then repeat: 7107 / 858

On to step 4:
If we divide 7107 by 858, we get 8 and a remainder of 243.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6864 away from 7107, we end up with 243.
Grab the next digit (6) from the dividend, add it to 243, then carry on: 2436 / 858

Moving on to step 5:
When dividing 2436 by 858, we get 2 with a remainder of 720.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 1716 away from 2436, we end up with 720.
Bring next digit (5) of the dividend behind the 720 and repeat the process: 7205 / 858

Advancing to step 6:
If we divide 7205 by 858, we get 8 and a remainder of 341.
Write down 8 as next digit of the result. 
Result so far: 828.0
Subtract 6864 from 7205 to get 341.
Include the next digit (8) from the dividend after 341, then repeat: 3418 / 858

Step 7:
When dividing 3418 by 858, we get 3 with a remainder of 844.
The next digit of our result is 3. 
Result so far: 8283.0
Deduct 2574 from 3418 and we're left with 844.
Bring next digit (9) of the dividend behind the 844 and repeat the process: 8449 / 858

Going ahead to step 8:
The number 858 fits into 8449 9 times, leaving a remainder of 727.
Use 9 as the next digit of our solution. 
Result so far: 82839.0
If we subtract 7722 from 8449, we get 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Moving on to step 9:
The number 858 fits into 7270 8 times, leaving a remainder of 406.
Record the quotient 8 as the next digit in the result. 
Result so far: 82839.8
The remainder is 406 after subtracting 6864 from 7270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 10:
4060 divided by 858 is 4 with a remainder of 628.
The number 4 becomes the next digit in our result. 
Result so far: 82839.84
Subtract 3432 from 4060 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 11:
When dividing 6280 by 858, we get 7 with a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 82839.847
If we subtract 6006 from 6280, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 12:
The number 858 fits into 2740 3 times, leaving a remainder of 166.
The next digit of our result is 3. 
Result so far: 82839.8473
The remainder is 166 after subtracting 2574 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 13:
858 goes into 1660 1 times with a remainder of 802.
Use 1 as the next digit of our solution. 
Result so far: 82839.84731
If we subtract 858 from 1660, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 14:
When dividing 8020 by 858, we get 9 with a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 82839.847319
The remainder is 298 after subtracting 7722 from 8020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 15:
When dividing 2980 by 858, we get 3 with a remainder of 406.
The next digit of our result is 3. 
Result so far: 82839.8473193
If we take 2574 away from 2980, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 16:
When dividing 4060 by 858, we get 4 with a remainder of 628.
The next digit of our result is 4. 
Result so far: 82839.84731934
If we subtract 3432 from 4060, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

The final outcome is 82839.84731934, with a leftover of 6.28e-07.
