We divide 81898804 by 142
The aim is to understand the frequency of 142 in 81898804.

Step 1:
When dividing 8 by 142, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 142

Going ahead to step 2:
142 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 142

Going ahead to step 3:
142 goes into 818 5 times with a remainder of 108.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 710 from 818 to get 108.
Bring next digit (9) of the dividend behind the 108 and repeat the process: 1089 / 142

On to step 4:
142 can be fit into 1089 7 times, resulting in a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 994 from 1089 leaves us with 95.
Take the next digit (8) from the dividend and append it to 95, then repeat: 958 / 142

Step 5:
142 goes into 958 6 times with a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
Deduct 852 from 958 and we're left with 106.
Bring next digit (8) of the dividend behind the 106 and repeat the process: 1068 / 142

Going ahead to step 6:
The number 142 fits into 1068 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 5767.0
Subtract 994 from 1068 to get 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 142

Moving on to step 7:
The number 142 fits into 740 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 57675.0
Subtract 710 from 740 to get 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 142

On to step 8:
The number 142 fits into 304 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 576752.0
The remainder is 20 after subtracting 284 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
142 goes into 200 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 576752.1
The remainder is 58 after subtracting 142 from 200.
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 10:
142 can be fit into 580 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 576752.14
Subtracting 568 from 580 leaves us 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.

Moving on to step 11:
142 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 576752.14
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
142 goes into 1200 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 576752.1408
Subtract 1136 from 1200 to 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 13:
The number 142 fits into 640 4 times, leaving a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 576752.14084
Deduct 568 from 640 and we're left 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.

Moving on to step 14:
The number 142 fits into 720 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 576752.140845
If we subtract 710 from 720, we 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.

Step 15:
The number 142 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 576752.140845
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
The number 142 fits into 1000 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 576752.14084507
Deduct 994 from 1000 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 576752.14084507 with a balance of 6e-09.
