68579986 ÷ 331 
We want to divide 68579986 by 331.

Step 1:
331 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 331

Let's proceed to step 2:
331 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 331

Let's proceed to step 3:
331 goes into 685 2 times with a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 662 from 685 and we're left with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 331

Moving on to step 4:
The number 331 fits into 237 0 times, leaving a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 237, we end up with 237.
Fetch the next digit (9) from the dividend, attach it to 237 and continue: 2379 / 331

Let's proceed to step 5:
When dividing 2379 by 331, we get 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 2317 away from 2379, we end up with 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 331

Going ahead to step 6:
If we divide 629 by 331, we get 1 and a remainder of 298.
Write down 1 as next digit of the result. 
Result so far: 2071.0
If we take 331 away from 629, we end up with 298.
Append the next digit (8) from the dividend to 298 and continue with: 2988 / 331

Let's proceed to step 7:
331 goes into 2988 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 20719.0
Subtracting 2979 from 2988 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 331

Let's proceed to step 8:
331 goes into 96 0 times with a remainder of 96.
The next digit of our result is 0. 
Result so far: 207190.0
The remainder is 96 after subtracting 0 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
960 divided by 331 is 2 with a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 207190.2
The remainder is 298 after subtracting 662 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 10:
The number 331 fits into 2980 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 207190.29
Subtracting 2979 from 2980 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
When dividing 10 by 331, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 207190.29
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
331 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 207190.29
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 207190.29, with a leftover of 0.001.
