We look at the division of 64031096 by 141 
The aim is to understand the frequency of 141 in 64031096.

On to step 1:
The number 141 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 141

Advancing to step 2:
The number 141 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 141

On to step 3:
If we divide 640 by 141, we get 4 and a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 564 from 640 and we're left with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 141

Moving on to step 4:
The number 141 fits into 763 5 times, leaving a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 705 from 763 leaves us with 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 141

On to step 5:
581 divided by 141 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
Subtract 564 from 581 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 141

Step 6:
141 goes into 170 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4541.0
Subtract 141 from 170 to get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 141

Step 7:
141 can be fit into 299 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 45412.0
Subtracting 282 from 299 leaves us with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 141

Let's proceed to step 8:
If we divide 176 by 141, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 454121.0
Deduct 141 from 176 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
350 divided by 141 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 454121.2
Deduct 282 from 350 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
If we divide 680 by 141, we get 4 and a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 454121.24
The remainder is 116 after subtracting 564 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
The number 141 fits into 1160 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 454121.248
Subtract 1128 from 1160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
141 goes into 320 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 454121.2482
Subtract 282 from 320 to 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 13:
If we divide 380 by 141, we get 2 and a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 454121.24822
The remainder is 98 after subtracting 282 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 454121.24822 and a remainder of 9.8e-05.
