We divide 86531933 by 131
The aim is to understand the frequency of 131 in 86531933.

Moving on to step 1:
8 divided by 131 is 0 with 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.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 131

On to step 2:
86 divided by 131 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 131

Going ahead to step 3:
865 divided by 131 is 6 with a remainder of 79.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 786 from 865 and we're left with 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 131

Advancing to step 4:
131 goes into 793 6 times with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 786 away from 793, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 131

Let's proceed to step 5:
If we divide 71 by 131, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 660.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 131

Step 6:
131 goes into 719 5 times with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 6605.0
The remainder is 64 after subtracting 655 from 719.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 131

Step 7:
643 divided by 131 is 4 with a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 66054.0
If we subtract 524 from 643, we get 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 131

Going ahead to step 8:
131 can be fit into 1193 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 660549.0
Subtract 1179 from 1193 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 131 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 660549.1
The remainder is 9 after subtracting 131 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
90 divided by 131 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 660549.1
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
If we divide 900 by 131, we get 6 and a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 660549.106
The remainder is 114 after subtracting 786 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 12:
When dividing 1140 by 131, we get 8 with a remainder of 92.
The next digit of our result is 8. 
Result so far: 660549.1068
If we take 1048 away from 1140, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
131 goes into 920 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 660549.10687
The remainder is 3 after subtracting 917 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
131 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 660549.10687
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 15:
300 divided by 131 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 660549.1068702
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.

On to step 16:
131 can be fit into 380 2 times, resulting in a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 660549.10687022
Subtract 262 from 380 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 660549.10687022, and the remainder is 1.18e-07.
