31545289 ÷ 681 
The aim is to understand the frequency of 681 in 31545289.

On to step 1:
If we divide 3 by 681, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 681

Let's proceed to step 2:
681 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 681

On to step 3:
If we divide 315 by 681, we get 0 and a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 315 leaves us with 315.
Bring next digit (4) of the dividend behind the 315 and repeat the process: 3154 / 681

Let's proceed to step 4:
3154 divided by 681 is 4 with a remainder of 430.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2724 from 3154, we get 430.
Take the next digit (5) from the dividend and append it to 430, then repeat: 4305 / 681

Advancing to step 5:
The number 681 fits into 4305 6 times, leaving a remainder of 219.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 4086 away from 4305, we end up with 219.
Fetch the next digit (2) from the dividend, attach it to 219 and continue: 2192 / 681

Advancing to step 6:
The number 681 fits into 2192 3 times, leaving a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 463.0
The remainder is 149 after subtracting 2043 from 2192.
Include the next digit (8) from the dividend after 149, then repeat: 1498 / 681

Step 7:
1498 divided by 681 is 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 4632.0
Deduct 1362 from 1498 and we're left with 136.
Grab the next digit (9) from the dividend, add it to 136, then carry on: 1369 / 681

Moving on to step 8:
681 goes into 1369 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 46322.0
Deduct 1362 from 1369 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
681 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 46322.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 681 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 46322.01
The remainder is 19 after subtracting 681 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
If we divide 190 by 681, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 46322.01
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
The number 681 fits into 1900 2 times, leaving a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 46322.0102
If we subtract 1362 from 1900, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 13:
The number 681 fits into 5380 7 times, leaving a remainder of 613.
The next digit of our result is 7. 
Result so far: 46322.01027
The remainder is 613 after subtracting 4767 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 14:
If we divide 6130 by 681, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 46322.010279
Deduct 6129 from 6130 and we're left 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.

Step 15:
When dividing 10 by 681, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 46322.010279
Deduct 0 from 10 and we're left 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.

On to step 16:
681 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 46322.010279
Subtract 0 from 100 to get 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 quotient of the division is 46322.010279, and the remainder is 1e-07.
