68908688 ÷ 858 
Our goal is to divide 68908688 by 858.

Let's proceed to step 1:
The number 858 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 858

Advancing to step 2:
When dividing 68 by 858, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 858

On to step 3:
858 goes into 689 0 times with a remainder of 689.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 689 leaves us with 689.
Fetch the next digit (0) from the dividend, attach it to 689 and continue: 6890 / 858

On to step 4:
858 goes into 6890 8 times with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6864 from 6890 to get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 858

Advancing to step 5:
858 goes into 268 0 times with a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 268 and we're left with 268.
Include the next digit (6) from the dividend after 268, then repeat: 2686 / 858

Let's proceed to step 6:
2686 divided by 858 is 3 with a remainder of 112.
The next digit of our result is 3. 
Result so far: 803.0
Subtract 2574 from 2686 to get 112.
Bring next digit (8) of the dividend behind the 112 and repeat the process: 1128 / 858

Step 7:
1128 divided by 858 is 1 with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 8031.0
Subtracting 858 from 1128 leaves us with 270.
Take the next digit (8) from the dividend and append it to 270, then repeat: 2708 / 858

On to step 8:
2708 divided by 858 is 3 with a remainder of 134.
Use 3 as the next digit of our solution. 
Result so far: 80313.0
If we subtract 2574 from 2708, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
858 goes into 1340 1 times with a remainder of 482.
The number 1 becomes the next digit in our result. 
Result so far: 80313.1
Deduct 858 from 1340 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 10:
The number 858 fits into 4820 5 times, leaving a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 80313.15
Subtract 4290 from 4820 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
When dividing 5300 by 858, we get 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 80313.156
If we take 5148 away from 5300, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 12:
858 can be fit into 1520 1 times, resulting in a remainder of 662.
Write down 1 as next digit of the result. 
Result so far: 80313.1561
Deduct 858 from 1520 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 13:
858 can be fit into 6620 7 times, resulting in a remainder of 614.
Put 7 as the next digit of the answer. 
Result so far: 80313.15617
Subtracting 6006 from 6620 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 14:
The number 858 fits into 6140 7 times, leaving a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 80313.156177
The remainder is 134 after subtracting 6006 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Our division results in 80313.156177 with a remaining 1.34e-05.
