66818299 ÷ 142 
The aim is to understand the frequency of 142 in 66818299.

Let's proceed to step 1:
142 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 142

Going ahead to step 2:
The number 142 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 142

Let's proceed to step 3:
The number 142 fits into 668 4 times, leaving a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 568 from 668 leaves us with 100.
Bring next digit (1) of the dividend behind the 100 and repeat the process: 1001 / 142

Step 4:
1001 divided by 142 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 994 away from 1001, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 142

Let's proceed to step 5:
142 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 470.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 142

Going ahead to step 6:
When dividing 782 by 142, we get 5 with a remainder of 72.
The next digit of our result is 5. 
Result so far: 4705.0
If we subtract 710 from 782, we get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 142

On to step 7:
142 goes into 729 5 times with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 47055.0
Deduct 710 from 729 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 142

Let's proceed to step 8:
199 divided by 142 is 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 470551.0
If we subtract 142 from 199, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
When dividing 570 by 142, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 470551.4
Subtracting 568 from 570 leaves us 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 10:
When dividing 20 by 142, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 470551.4
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 11:
The number 142 fits into 200 1 times, leaving a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 470551.401
Deduct 142 from 200 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
142 goes into 580 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 470551.4014
Deduct 568 from 580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
The number 142 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 470551.4014
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
1200 divided by 142 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 470551.401408
If we subtract 1136 from 1200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
When dividing 640 by 142, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 470551.4014084
Subtracting 568 from 640 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
720 divided by 142 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 470551.40140845
Subtract 710 from 720 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 470551.40140845 and a remainder of 1e-08.
