33074921 ÷ 141 
The aim is to understand the frequency of 141 in 33074921.

Step 1:
The number 141 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 141

Moving on to step 2:
If we divide 33 by 141, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 141

Going ahead to step 3:
141 goes into 330 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 282 from 330 to get 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 141

Step 4:
141 goes into 487 3 times with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 423 from 487 leaves us with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 141

On to step 5:
644 divided by 141 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Subtract 564 from 644 to get 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 141

Advancing to step 6:
809 divided by 141 is 5 with a remainder of 104.
The next digit of our result is 5. 
Result so far: 2345.0
If we subtract 705 from 809, we get 104.
Append the next digit (2) from the dividend to 104 and continue with: 1042 / 141

On to step 7:
When dividing 1042 by 141, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 23457.0
The remainder is 55 after subtracting 987 from 1042.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 141

Let's proceed to step 8:
551 divided by 141 is 3 with a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 234573.0
Subtracting 423 from 551 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
1280 divided by 141 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 234573.9
If we take 1269 away from 1280, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
110 divided by 141 is 0 with a remainder of 110.
The next digit of our result is 0. 
Result so far: 234573.9
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
The number 141 fits into 1100 7 times, leaving a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 234573.907
Deduct 987 from 1100 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 12:
1130 divided by 141 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 234573.9078
If we take 1128 away from 1130, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
If we divide 20 by 141, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 234573.9078
Deduct 0 from 20 and we're left 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.

On to step 14:
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: 234573.907801
If we take 141 away from 200, we end up 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.

On to step 15:
590 divided by 141 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 234573.9078014
Subtracting 564 from 590 leaves us 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 16:
141 goes into 260 1 times with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 234573.90780141
Deduct 141 from 260 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The quotient of the division is 234573.90780141, and the remainder is 1.19e-07.
