30177909 ÷ 142 
The aim is to understand the frequency of 142 in 30177909.

Let's proceed to step 1:
142 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 142

Step 2:
If we divide 30 by 142, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 142

Advancing to step 3:
If we divide 301 by 142, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 284 away from 301, we end up with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 142

Let's proceed to step 4:
177 divided by 142 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 142 from 177 leaves us with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 142

On to step 5:
142 goes into 357 2 times with a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Subtract 284 from 357 to get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 142

Advancing to step 6:
The number 142 fits into 739 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 2125.0
Subtract 710 from 739 to get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 142

Let's proceed to step 7:
If we divide 290 by 142, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 21252.0
Subtracting 284 from 290 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 142

Step 8:
If we divide 69 by 142, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 212520.0
If we take 0 away from 69, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
142 can be fit into 690 4 times, resulting in a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 212520.4
Deduct 568 from 690 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
When dividing 1220 by 142, we get 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 212520.48
Deduct 1136 from 1220 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
If we divide 840 by 142, we get 5 and a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 212520.485
If we subtract 710 from 840, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 12:
142 goes into 1300 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 212520.4859
Deduct 1278 from 1300 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
When dividing 220 by 142, we get 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 212520.48591
Deduct 142 from 220 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
142 can be fit into 780 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 212520.485915
Deduct 710 from 780 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
142 goes into 700 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 212520.4859154
Subtracting 568 from 700 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 16:
The number 142 fits into 1320 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 212520.48591549
If we subtract 1278 from 1320, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 212520.48591549 with a balance of 4.2e-08.
