We divide 64436561 by 131
The aim is to understand the frequency of 131 in 64436561.

Going ahead to step 1:
The number 131 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 131

Advancing to step 2:
64 divided by 131 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 131

Let's proceed to step 3:
The number 131 fits into 644 4 times, leaving a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 524 away from 644, we end up with 120.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 131

Let's proceed to step 4:
1203 divided by 131 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 1179 away from 1203, we end up with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 131

Moving on to step 5:
131 goes into 246 1 times with a remainder of 115.
The next digit of our result is 1. 
Result so far: 491.0
If we subtract 131 from 246, we get 115.
Include the next digit (5) from the dividend after 115, then repeat: 1155 / 131

Going ahead to step 6:
When dividing 1155 by 131, we get 8 with a remainder of 107.
The number 8 becomes the next digit in our result. 
Result so far: 4918.0
Subtract 1048 from 1155 to get 107.
Bring next digit (6) of the dividend behind the 107 and repeat the process: 1076 / 131

Let's proceed to step 7:
When dividing 1076 by 131, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 49188.0
Subtracting 1048 from 1076 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 131

Moving on to step 8:
131 can be fit into 281 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 491882.0
If we take 262 away from 281, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 131, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 491882.1
Deduct 131 from 190 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
When dividing 590 by 131, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 491882.14
The remainder is 66 after subtracting 524 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
When dividing 660 by 131, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 491882.145
The remainder is 5 after subtracting 655 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
131 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 491882.145
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
131 goes into 500 3 times with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 491882.14503
If we subtract 393 from 500, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 14:
131 can be fit into 1070 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 491882.145038
If we subtract 1048 from 1070, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 15:
When dividing 220 by 131, we get 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 491882.1450381
If we subtract 131 from 220, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 16:
If we divide 890 by 131, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 491882.14503816
Subtract 786 from 890 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 491882.14503816 with a remaining 1.04e-07.
