We look at the division of 36563485 by 131 
The aim is to understand the frequency of 131 in 36563485.

Going ahead to step 1:
131 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 131

Step 2:
When dividing 36 by 131, we get 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 131

On to step 3:
The number 131 fits into 365 2 times, leaving a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 262 from 365 leaves us with 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 131

Going ahead to step 4:
The number 131 fits into 1036 7 times, leaving a remainder of 119.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 917 from 1036, we get 119.
Fetch the next digit (3) from the dividend, attach it to 119 and continue: 1193 / 131

Going ahead to step 5:
1193 divided by 131 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
Deduct 1179 from 1193 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 131

Advancing to step 6:
131 can be fit into 144 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 2791.0
If we take 131 away from 144, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 131

On to step 7:
When dividing 138 by 131, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 27911.0
If we take 131 away from 138, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 131

Let's proceed to step 8:
131 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 279110.0
Deduct 0 from 75 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
750 divided by 131 is 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 279110.5
The remainder is 95 after subtracting 655 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 10:
950 divided by 131 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 279110.57
If we take 917 away from 950, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
The number 131 fits into 330 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 279110.572
The remainder is 68 after subtracting 262 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
131 can be fit into 680 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 279110.5725
If we take 655 away from 680, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
When dividing 250 by 131, we get 1 with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 279110.57251
The remainder is 119 after subtracting 131 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 14:
131 can be fit into 1190 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 279110.572519
Subtract 1179 from 1190 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
110 divided by 131 is 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 279110.572519
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
1100 divided by 131 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 279110.57251908
Subtracting 1048 from 1100 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 279110.57251908 and a remainder of 5.2e-08.
