Let's divide 19847907 by 143
The aim is to understand the frequency of 143 in 19847907.

Moving on to step 1:
143 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 143

Going ahead to step 2:
143 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 143

Going ahead to step 3:
143 goes into 198 1 times with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 143 from 198 and we're left with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 143

Moving on to step 4:
143 goes into 554 3 times with a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 429 from 554 to get 125.
Grab the next digit (7) from the dividend, add it to 125, then carry on: 1257 / 143

Moving on to step 5:
1257 divided by 143 is 8 with a remainder of 113.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 1144 from 1257, we get 113.
Fetch the next digit (9) from the dividend, attach it to 113 and continue: 1139 / 143

Step 6:
143 goes into 1139 7 times with a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 1387.0
The remainder is 138 after subtracting 1001 from 1139.
Fetch the next digit (0) from the dividend, attach it to 138 and continue: 1380 / 143

Going ahead to step 7:
143 can be fit into 1380 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 13879.0
The remainder is 93 after subtracting 1287 from 1380.
Include the next digit (7) from the dividend after 93, then repeat: 937 / 143

Moving on to step 8:
143 can be fit into 937 6 times, resulting in a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 138796.0
Deduct 858 from 937 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
143 can be fit into 790 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 138796.5
Subtracting 715 from 790 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
143 can be fit into 750 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 138796.55
If we subtract 715 from 750, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 138796.55 and a remainder of 0.035.
