Let's divide 143388 by 85
The aim is to understand the frequency of 85 in 143388.

Going ahead to step 1:
1 divided by 85 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 85

Going ahead to step 2:
85 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 85

Let's proceed to step 3:
143 divided by 85 is 1 with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 85 from 143, we get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 85

Going ahead to step 4:
The number 85 fits into 583 6 times, leaving a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 510 from 583 to get 73.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 85

Step 5:
85 goes into 738 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Subtract 680 from 738 to get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 85

Moving on to step 6:
If we divide 588 by 85, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 1686.0
Subtract 510 from 588 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
If we divide 780 by 85, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1686.9
Subtracting 765 from 780 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1686.91
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
650 divided by 85 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 1686.917
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
If we divide 550 by 85, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1686.9176
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 85 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 1686.91764
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1686.917647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
The number 85 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 1686.917647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
500 divided by 85 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1686.91764705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

In conclusion, the division gives 1686.91764705 with a balance of 7.5e-08.
