We look at the division of 83964793 by 131 
The aim is to understand the frequency of 131 in 83964793.

Going ahead to step 1:
If we divide 8 by 131, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 131

Advancing to step 2:
131 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 131

Going ahead to step 3:
The number 131 fits into 839 6 times, leaving a remainder of 53.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 786 from 839, we get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 131

Step 4:
The number 131 fits into 536 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 524 from 536 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 131

Moving on to step 5:
If we divide 124 by 131, we get 0 and a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 640.0
Deduct 0 from 124 and we're left with 124.
Fetch the next digit (7) from the dividend, attach it to 124 and continue: 1247 / 131

Going ahead to step 6:
When dividing 1247 by 131, we get 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 6409.0
If we subtract 1179 from 1247, we get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 131

Going ahead to step 7:
689 divided by 131 is 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 64095.0
If we take 655 away from 689, we end up with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 131

Let's proceed to step 8:
The number 131 fits into 343 2 times, leaving a remainder of 81.
The next digit of our result is 2. 
Result so far: 640952.0
Deduct 262 from 343 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
810 divided by 131 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 640952.6
The remainder is 24 after subtracting 786 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 131, we get 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 640952.61
Subtracting 131 from 240 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 11:
1090 divided by 131 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 640952.618
If we subtract 1048 from 1090, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
When dividing 420 by 131, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 640952.6183
Deduct 393 from 420 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
131 can be fit into 270 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 640952.61832
Subtracting 262 from 270 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
If we divide 80 by 131, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 640952.61832
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
When dividing 800 by 131, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 640952.6183206
Deduct 786 from 800 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 16:
131 goes into 140 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 640952.61832061
Subtracting 131 from 140 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 640952.61832061, and the remainder is 9e-09.
