We're dividing 75306701 by 143 
The aim is to understand the frequency of 143 in 75306701.

On to step 1:
The number 143 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 143

Step 2:
143 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 143

Step 3:
143 can be fit into 753 5 times, resulting in a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 38 after subtracting 715 from 753.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 143

Going ahead to step 4:
143 can be fit into 380 2 times, resulting in a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 286 from 380 leaves us with 94.
Grab the next digit (6) from the dividend, add it to 94, then carry on: 946 / 143

Moving on to step 5:
The number 143 fits into 946 6 times, leaving a remainder of 88.
The next digit of our result is 6. 
Result so far: 526.0
Deduct 858 from 946 and we're left with 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 143

Let's proceed to step 6:
The number 143 fits into 887 6 times, leaving a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 5266.0
Subtract 858 from 887 to get 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 143

Going ahead to step 7:
143 can be fit into 290 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 52662.0
If we subtract 286 from 290, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 143

On to step 8:
The number 143 fits into 41 0 times, leaving a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 526620.0
Subtracting 0 from 41 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
When dividing 410 by 143, we get 2 with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 526620.2
Subtracting 286 from 410 leaves us 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.

Step 10:
143 goes into 1240 8 times with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 526620.28
Subtract 1144 from 1240 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
143 can be fit into 960 6 times, resulting in a remainder of 102.
The next digit of our result is 6. 
Result so far: 526620.286
Deduct 858 from 960 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
When dividing 1020 by 143, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 526620.2867
Subtracting 1001 from 1020 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 143 fits into 190 1 times, leaving a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 526620.28671
If we subtract 143 from 190, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
If we divide 470 by 143, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 526620.286713
Subtract 429 from 470 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 15:
If we divide 410 by 143, we get 2 and a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 526620.2867132
The remainder is 124 after subtracting 286 from 410.
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 16:
If we divide 1240 by 143, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 526620.28671328
If we subtract 1144 from 1240, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 526620.28671328 with a balance of 9.6e-08.
