136461 divided by 31 
The aim is to understand the frequency of 31 in 136461.

On to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 31

On to step 2:
If we divide 13 by 31, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 31

Advancing to step 3:
The number 31 fits into 136 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 124 away from 136, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 31

Let's proceed to step 4:
31 goes into 124 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 124 away from 124, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 31

Going ahead to step 5:
When dividing 6 by 31, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 440.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 31

On to step 6:
If we divide 61 by 31, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 4401.0
The remainder is 30 after subtracting 31 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 31, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 4401.9
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
31 goes into 210 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4401.96
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 31 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 4401.967
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
230 divided by 31 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 4401.9677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 4401.9677 and a remainder of 0.00013.
