We're dividing 89417380 by 143 
The aim is to understand the frequency of 143 in 89417380.

Advancing to step 1:
143 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 143

Advancing to step 2:
When dividing 89 by 143, we get 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (4) from the dividend, add it to 89, then carry on: 894 / 143

Step 3:
143 can be fit into 894 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 858 from 894 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 143

Advancing to step 4:
If we divide 361 by 143, we get 2 and a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
The remainder is 75 after subtracting 286 from 361.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 143

Step 5:
757 divided by 143 is 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 625.0
Subtract 715 from 757 to get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 143

Step 6:
143 can be fit into 423 2 times, resulting in a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 6252.0
If we subtract 286 from 423, we get 137.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 143

Let's proceed to step 7:
143 goes into 1378 9 times with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 62529.0
If we take 1287 away from 1378, we end up with 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 143

Going ahead to step 8:
143 goes into 910 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 625296.0
Deduct 858 from 910 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
The number 143 fits into 520 3 times, leaving a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 625296.3
Subtracting 429 from 520 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
143 can be fit into 910 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 625296.36
If we subtract 858 from 910, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
143 goes into 520 3 times with a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 625296.363
If we subtract 429 from 520, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
143 can be fit into 910 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 625296.3636
Subtract 858 from 910 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
520 divided by 143 is 3 with a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 625296.36363
The remainder is 91 after subtracting 429 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 14:
The number 143 fits into 910 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 625296.363636
Deduct 858 from 910 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
If we divide 520 by 143, we get 3 and a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 625296.3636363
Subtracting 429 from 520 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 16:
143 goes into 910 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 625296.36363636
Subtracting 858 from 910 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 625296.36363636, and the remainder is 5.2e-08.
