We're dividing 91669833 by 131 
The aim is to understand the frequency of 131 in 91669833.

On to step 1:
The number 131 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 131

On to step 2:
When dividing 91 by 131, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 131

Going ahead to step 3:
The number 131 fits into 916 6 times, leaving a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 786 from 916 and we're left with 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 131

Moving on to step 4:
1306 divided by 131 is 9 with a remainder of 127.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 1179 from 1306 to get 127.
Take the next digit (9) from the dividend and append it to 127, then repeat: 1279 / 131

Going ahead to step 5:
If we divide 1279 by 131, we get 9 and a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 699.0
Subtracting 1179 from 1279 leaves us with 100.
Take the next digit (8) from the dividend and append it to 100, then repeat: 1008 / 131

Going ahead to step 6:
If we divide 1008 by 131, we get 7 and a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 6997.0
If we subtract 917 from 1008, we get 91.
Append the next digit (3) from the dividend to 91 and continue with: 913 / 131

Let's proceed to step 7:
131 goes into 913 6 times with a remainder of 127.
Write down 6 as next digit of the result. 
Result so far: 69976.0
The remainder is 127 after subtracting 786 from 913.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 131

Let's proceed to step 8:
When dividing 1273 by 131, we get 9 with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 699769.0
Subtract 1179 from 1273 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 9:
131 goes into 940 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 699769.7
The remainder is 23 after subtracting 917 from 940.
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:
131 goes into 230 1 times with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 699769.71
If we subtract 131 from 230, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 11:
The number 131 fits into 990 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 699769.717
If we take 917 away from 990, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 12:
730 divided by 131 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 699769.7175
Deduct 655 from 730 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.

Advancing to step 13:
If we divide 750 by 131, we get 5 and a remainder of 95.
The next digit of our result is 5. 
Result so far: 699769.71755
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.

After the division, we end up with 699769.71755 and a remainder of 9.5e-05.
