We look at the division of 80668335 by 131 
We want to divide 80668335 by 131.

On to step 1:
The number 131 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 131

Step 2:
131 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 131

On to step 3:
The number 131 fits into 806 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 786 away from 806, we end up with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 131

On to step 4:
The number 131 fits into 206 1 times, leaving a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Deduct 131 from 206 and we're left with 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 131

Going ahead to step 5:
When dividing 758 by 131, we get 5 with a remainder of 103.
The number 5 becomes the next digit in our result. 
Result so far: 615.0
If we subtract 655 from 758, we get 103.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 131

Let's proceed to step 6:
131 can be fit into 1033 7 times, resulting in a remainder of 116.
Use 7 as the next digit of our solution. 
Result so far: 6157.0
Subtract 917 from 1033 to get 116.
Take the next digit (3) from the dividend and append it to 116, then repeat: 1163 / 131

Going ahead to step 7:
If we divide 1163 by 131, we get 8 and a remainder of 115.
The next digit of our result is 8. 
Result so far: 61578.0
If we take 1048 away from 1163, we end up with 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 131

Let's proceed to step 8:
The number 131 fits into 1155 8 times, leaving a remainder of 107.
Use 8 as the next digit of our solution. 
Result so far: 615788.0
Deduct 1048 from 1155 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 9:
131 can be fit into 1070 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 615788.8
The remainder is 22 after subtracting 1048 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
131 can be fit into 220 1 times, resulting in a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 615788.81
Deduct 131 from 220 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 11:
When dividing 890 by 131, we get 6 with a remainder of 104.
The next digit of our result is 6. 
Result so far: 615788.816
If we subtract 786 from 890, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
131 can be fit into 1040 7 times, resulting in a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 615788.8167
Subtracting 917 from 1040 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 13:
1230 divided by 131 is 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 615788.81679
Deduct 1179 from 1230 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 14:
131 goes into 510 3 times with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 615788.816793
Subtract 393 from 510 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 15:
1170 divided by 131 is 8 with a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 615788.8167938
The remainder is 122 after subtracting 1048 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 16:
If we divide 1220 by 131, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 615788.81679389
Subtract 1179 from 1220 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 615788.81679389 with a balance of 4.1e-08.
