Let's divide 21819646 by 142
The aim is to understand the frequency of 142 in 21819646.

Moving on to step 1:
2 divided by 142 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 142

On to step 2:
If we divide 21 by 142, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 142

Advancing to step 3:
142 can be fit into 218 1 times, resulting in a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 142 from 218 leaves us with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 142

Step 4:
If we divide 761 by 142, we get 5 and a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 710 from 761 leaves us with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 142

Advancing to step 5:
The number 142 fits into 519 3 times, leaving a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
The remainder is 93 after subtracting 426 from 519.
Fetch the next digit (6) from the dividend, attach it to 93 and continue: 936 / 142

Step 6:
The number 142 fits into 936 6 times, leaving a remainder of 84.
The next digit of our result is 6. 
Result so far: 1536.0
Deduct 852 from 936 and we're left with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 142

Advancing to step 7:
The number 142 fits into 844 5 times, leaving a remainder of 134.
Write down 5 as next digit of the result. 
Result so far: 15365.0
The remainder is 134 after subtracting 710 from 844.
Fetch the next digit (6) from the dividend, attach it to 134 and continue: 1346 / 142

Advancing to step 8:
1346 divided by 142 is 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 153659.0
Subtract 1278 from 1346 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
If we divide 680 by 142, we get 4 and a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 153659.4
Subtracting 568 from 680 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
The number 142 fits into 1120 7 times, leaving a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 153659.47
The remainder is 126 after subtracting 994 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
When dividing 1260 by 142, we get 8 with a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 153659.478
Deduct 1136 from 1260 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 12:
If we divide 1240 by 142, we get 8 and a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 153659.4788
Subtracting 1136 from 1240 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 153659.4788 with a remaining 0.00104.
