40541843 ÷ 141 
The aim is to understand the frequency of 141 in 40541843.

Advancing to step 1:
141 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 141

Moving on to step 2:
If we divide 40 by 141, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 141

Moving on to step 3:
141 can be fit into 405 2 times, resulting in a remainder of 123.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 282 away from 405, we end up with 123.
Bring next digit (4) of the dividend behind the 123 and repeat the process: 1234 / 141

On to step 4:
The number 141 fits into 1234 8 times, leaving a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 1128 from 1234 and we're left with 106.
Fetch the next digit (1) from the dividend, attach it to 106 and continue: 1061 / 141

Advancing to step 5:
141 goes into 1061 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 287.0
Deduct 987 from 1061 and we're left with 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 141

Advancing to step 6:
141 goes into 748 5 times with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 2875.0
If we subtract 705 from 748, we get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 141

Advancing to step 7:
The number 141 fits into 434 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 28753.0
Deduct 423 from 434 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 141

Let's proceed to step 8:
141 can be fit into 113 0 times, resulting in a remainder of 113.
Use 0 as the next digit of our solution. 
Result so far: 287530.0
If we subtract 0 from 113, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
If we divide 1130 by 141, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 287530.8
Subtract 1128 from 1130 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 141, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 287530.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 141, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 287530.801
If we subtract 141 from 200, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
141 goes into 590 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 287530.8014
If we take 564 away from 590, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
141 can be fit into 260 1 times, resulting in a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 287530.80141
The remainder is 119 after subtracting 141 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 14:
141 goes into 1190 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 287530.801418
If we take 1128 away from 1190, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
If we divide 620 by 141, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 287530.8014184
If we take 564 away from 620, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
When dividing 560 by 141, we get 3 with a remainder of 137.
The next digit of our result is 3. 
Result so far: 287530.80141843
Subtract 423 from 560 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 287530.80141843, with a leftover of 1.37e-07.
