We're dividing 73638337 by 131 
The aim is to understand the frequency of 131 in 73638337.

Let's proceed to step 1:
If we divide 7 by 131, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 131

On to step 2:
If we divide 73 by 131, we get 0 and a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 131

Moving on to step 3:
If we divide 736 by 131, we get 5 and a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 655 away from 736, we end up with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 131

Let's proceed to step 4:
When dividing 813 by 131, we get 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we take 786 away from 813, we end up with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 131

Step 5:
The number 131 fits into 278 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 562.0
The remainder is 16 after subtracting 262 from 278.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 131

Going ahead to step 6:
163 divided by 131 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 5621.0
If we subtract 131 from 163, we get 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 131

Moving on to step 7:
131 goes into 323 2 times with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 56212.0
Subtract 262 from 323 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 131

Advancing to step 8:
131 goes into 617 4 times with a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 562124.0
Subtracting 524 from 617 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
131 goes into 930 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 562124.7
Deduct 917 from 930 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
131 goes into 130 0 times with a remainder of 130.
The next digit of our result is 0. 
Result so far: 562124.7
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
131 can be fit into 1300 9 times, resulting in a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 562124.709
Subtract 1179 from 1300 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 12:
When dividing 1210 by 131, we get 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 562124.7099
If we subtract 1179 from 1210, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 562124.7099 and a remainder of 0.00031.
