81941711 ÷ 681 
The aim is to understand the frequency of 681 in 81941711.

Moving on to step 1:
The number 681 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 681

On to step 2:
681 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 681

Moving on to step 3:
681 goes into 819 1 times with a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 681 from 819 leaves us with 138.
Take the next digit (4) from the dividend and append it to 138, then repeat: 1384 / 681

Going ahead to step 4:
If we divide 1384 by 681, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1362 from 1384 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 681

Going ahead to step 5:
If we divide 221 by 681, we get 0 and a remainder of 221.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we take 0 away from 221, we end up with 221.
Grab the next digit (7) from the dividend, add it to 221, then carry on: 2217 / 681

On to step 6:
681 goes into 2217 3 times with a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 1203.0
The remainder is 174 after subtracting 2043 from 2217.
Append the next digit (1) from the dividend to 174 and continue with: 1741 / 681

Step 7:
If we divide 1741 by 681, we get 2 and a remainder of 379.
Use 2 as the next digit of our solution. 
Result so far: 12032.0
If we subtract 1362 from 1741, we get 379.
Grab the next digit (1) from the dividend, add it to 379, then carry on: 3791 / 681

Step 8:
681 can be fit into 3791 5 times, resulting in a remainder of 386.
Put 5 as the next digit of the answer. 
Result so far: 120325.0
Deduct 3405 from 3791 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
681 can be fit into 3860 5 times, resulting in a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 120325.5
Subtracting 3405 from 3860 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 10:
If we divide 4550 by 681, we get 6 and a remainder of 464.
Write down 6 as next digit of the result. 
Result so far: 120325.56
Deduct 4086 from 4550 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 11:
If we divide 4640 by 681, we get 6 and a remainder of 554.
Use 6 as the next digit of our solution. 
Result so far: 120325.566
If we subtract 4086 from 4640, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

The final result is 120325.566 with a remainder of 0.0554.
