Let's divide 743593 by 87
The aim is to understand the frequency of 87 in 743593.

Moving on to step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 87

Let's proceed to step 2:
The number 87 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 87

Step 3:
87 goes into 743 8 times with a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 696 from 743 and we're left with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 87

Step 4:
87 goes into 475 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 435 from 475, we get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 87

Going ahead to step 5:
If we divide 409 by 87, we get 4 and a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Subtracting 348 from 409 leaves us with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 87

Let's proceed to step 6:
When dividing 613 by 87, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 8547.0
Subtracting 609 from 613 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8547.0
If we take 0 away from 40, we end up 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.

Let's proceed to step 8:
If we divide 400 by 87, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 8547.04
The remainder is 52 after subtracting 348 from 400.
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:
If we divide 520 by 87, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 8547.045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
When dividing 850 by 87, we get 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 8547.0459
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
87 goes into 670 7 times with a remainder of 61.
The next digit of our result is 7. 
Result so far: 8547.04597
If we subtract 609 from 670, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
87 goes into 610 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 8547.045977
If we subtract 609 from 610, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 8547.045977 and a remainder of 1e-07.
