Let's divide 81198876 by 686
We want to figure out the number of times 81198876 can be divided by 686.

On to step 1:
The number 686 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 686

Advancing to step 2:
When dividing 81 by 686, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 686

Step 3:
If we divide 811 by 686, we get 1 and a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 686 away from 811, we end up with 125.
Bring next digit (9) of the dividend behind the 125 and repeat the process: 1259 / 686

Advancing to step 4:
When dividing 1259 by 686, we get 1 with a remainder of 573.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 686 away from 1259, we end up with 573.
Include the next digit (8) from the dividend after 573, then repeat: 5738 / 686

Let's proceed to step 5:
When dividing 5738 by 686, we get 8 with a remainder of 250.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtracting 5488 from 5738 leaves us with 250.
Append the next digit (8) from the dividend to 250 and continue with: 2508 / 686

On to step 6:
2508 divided by 686 is 3 with a remainder of 450.
Write down 3 as next digit of the result. 
Result so far: 1183.0
Deduct 2058 from 2508 and we're left with 450.
Append the next digit (7) from the dividend to 450 and continue with: 4507 / 686

On to step 7:
4507 divided by 686 is 6 with a remainder of 391.
The next digit of our result is 6. 
Result so far: 11836.0
If we take 4116 away from 4507, we end up with 391.
Fetch the next digit (6) from the dividend, attach it to 391 and continue: 3916 / 686

Going ahead to step 8:
The number 686 fits into 3916 5 times, leaving a remainder of 486.
Put 5 as the next digit of the answer. 
Result so far: 118365.0
Subtracting 3430 from 3916 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 9:
When dividing 4860 by 686, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 118365.7
Deduct 4802 from 4860 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
686 goes into 580 0 times with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 118365.7
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 11:
686 can be fit into 5800 8 times, resulting in a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 118365.708
Subtract 5488 from 5800 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
When dividing 3120 by 686, we get 4 with a remainder of 376.
Use 4 as the next digit of our solution. 
Result so far: 118365.7084
Subtracting 2744 from 3120 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 13:
686 goes into 3760 5 times with a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 118365.70845
Subtract 3430 from 3760 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
The number 686 fits into 3300 4 times, leaving a remainder of 556.
Write down 4 as next digit of the result. 
Result so far: 118365.708454
If we take 2744 away from 3300, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 15:
If we divide 5560 by 686, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 118365.7084548
If we subtract 5488 from 5560, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
The number 686 fits into 720 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 118365.70845481
The remainder is 34 after subtracting 686 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 118365.70845481, with a leftover of 3.4e-08.
