71863887 divided by 142 
The aim is to understand the frequency of 142 in 71863887.

Moving on to step 1:
142 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 142

Step 2:
71 divided by 142 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 142

Advancing to step 3:
The number 142 fits into 718 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 710 from 718, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 142

Let's proceed to step 4:
142 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 142

Advancing to step 5:
If we divide 863 by 142, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 506.0
Deduct 852 from 863 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 142

Going ahead to step 6:
142 goes into 118 0 times with a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 5060.0
If we take 0 away from 118, we end up with 118.
Take the next digit (8) from the dividend and append it to 118, then repeat: 1188 / 142

Step 7:
The number 142 fits into 1188 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 50608.0
Subtracting 1136 from 1188 leaves us with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 142

Let's proceed to step 8:
If we divide 527 by 142, we get 3 and a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 506083.0
Deduct 426 from 527 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
142 can be fit into 1010 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 506083.7
Deduct 994 from 1010 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 142 fits into 160 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 506083.71
If we take 142 away from 160, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
142 can be fit into 180 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 506083.711
If we subtract 142 from 180, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 506083.711, and the remainder is 0.0038.
