We're dividing 81526586 by 141 
The aim is to understand the frequency of 141 in 81526586.

Step 1:
The number 141 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 141

Advancing to step 2:
The number 141 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 141

Going ahead to step 3:
141 goes into 815 5 times with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 705 from 815, we get 110.
Take the next digit (2) from the dividend and append it to 110, then repeat: 1102 / 141

Moving on to step 4:
When dividing 1102 by 141, we get 7 with a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 987 from 1102 to get 115.
Take the next digit (6) from the dividend and append it to 115, then repeat: 1156 / 141

Moving on to step 5:
141 can be fit into 1156 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 578.0
The remainder is 28 after subtracting 1128 from 1156.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 141

Let's proceed to step 6:
285 divided by 141 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 5782.0
If we take 282 away from 285, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 141

Advancing to step 7:
If we divide 38 by 141, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 57820.0
Subtract 0 from 38 to get 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 141

Going ahead to step 8:
386 divided by 141 is 2 with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 578202.0
Subtract 282 from 386 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.

Advancing to step 9:
141 can be fit into 1040 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 578202.7
If we take 987 away from 1040, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
If we divide 530 by 141, we get 3 and a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 578202.73
Deduct 423 from 530 and we're left with 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 11:
1070 divided by 141 is 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 578202.737
Subtract 987 from 1070 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 12:
830 divided by 141 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 578202.7375
If we subtract 705 from 830, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 13:
1250 divided by 141 is 8 with a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 578202.73758
Subtract 1128 from 1250 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 14:
The number 141 fits into 1220 8 times, leaving a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 578202.737588
Subtract 1128 from 1220 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 578202.737588 with a remaining 9.2e-06.
