Let's divide 86370476 by 131
The aim is to understand the frequency of 131 in 86370476.

Going ahead to step 1:
When dividing 8 by 131, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 131

Advancing to step 2:
The number 131 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 131

On to step 3:
The number 131 fits into 863 6 times, leaving a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 786 from 863 and we're left with 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 131

Step 4:
When dividing 777 by 131, we get 5 with a remainder of 122.
The next digit of our result is 5. 
Result so far: 65.0
Deduct 655 from 777 and we're left with 122.
Append the next digit (0) from the dividend to 122 and continue with: 1220 / 131

Going ahead to step 5:
131 can be fit into 1220 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
The remainder is 41 after subtracting 1179 from 1220.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 131

Step 6:
131 goes into 414 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 6593.0
Subtract 393 from 414 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 131

Moving on to step 7:
If we divide 217 by 131, we get 1 and a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 65931.0
The remainder is 86 after subtracting 131 from 217.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 131

Advancing to step 8:
If we divide 866 by 131, we get 6 and a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 659316.0
The remainder is 80 after subtracting 786 from 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
131 goes into 800 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 659316.6
Subtracting 786 from 800 leaves us 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 10:
131 can be fit into 140 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 659316.61
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.

Going ahead to step 11:
90 divided by 131 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 659316.61
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
131 can be fit into 900 6 times, resulting in a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 659316.6106
If we subtract 786 from 900, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 13:
131 can be fit into 1140 8 times, resulting in a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 659316.61068
The remainder is 92 after subtracting 1048 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 14:
If we divide 920 by 131, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 659316.610687
Subtract 917 from 920 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
131 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 659316.610687
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
131 can be fit into 300 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 659316.61068702
If we subtract 262 from 300, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 659316.61068702 with a balance of 3.8e-08.
