80674980 ÷ 681 
The aim is to understand the frequency of 681 in 80674980.

On to step 1:
681 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 681

Moving on to step 2:
When dividing 80 by 681, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 681

Let's proceed to step 3:
806 divided by 681 is 1 with a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 681 from 806 leaves us with 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 681

Let's proceed to step 4:
681 goes into 1257 1 times with a remainder of 576.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 681 from 1257 leaves us with 576.
Fetch the next digit (4) from the dividend, attach it to 576 and continue: 5764 / 681

Going ahead to step 5:
If we divide 5764 by 681, we get 8 and a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 118.0
The remainder is 316 after subtracting 5448 from 5764.
Take the next digit (9) from the dividend and append it to 316, then repeat: 3169 / 681

On to step 6:
If we divide 3169 by 681, we get 4 and a remainder of 445.
Use 4 as the next digit of our solution. 
Result so far: 1184.0
Subtracting 2724 from 3169 leaves us with 445.
Append the next digit (8) from the dividend to 445 and continue with: 4458 / 681

On to step 7:
When dividing 4458 by 681, we get 6 with a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 11846.0
Subtracting 4086 from 4458 leaves us with 372.
Grab the next digit (0) from the dividend, add it to 372, then carry on: 3720 / 681

Let's proceed to step 8:
If we divide 3720 by 681, we get 5 and a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 118465.0
The remainder is 315 after subtracting 3405 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 9:
If we divide 3150 by 681, we get 4 and a remainder of 426.
Put 4 as the next digit of the answer. 
Result so far: 118465.4
Deduct 2724 from 3150 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 10:
681 goes into 4260 6 times with a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 118465.46
Subtract 4086 from 4260 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
If we divide 1740 by 681, we get 2 and a remainder of 378.
The number 2 becomes the next digit in our result. 
Result so far: 118465.462
Subtract 1362 from 1740 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 12:
3780 divided by 681 is 5 with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 118465.4625
If we subtract 3405 from 3780, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 13:
When dividing 3750 by 681, we get 5 with a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 118465.46255
If we take 3405 away from 3750, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 118465.46255 with a remaining 0.000345.
