Let's divide 393676 by 87
The aim is to understand the frequency of 87 in 393676.

Let's proceed to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 87

Going ahead to step 2:
If we divide 39 by 87, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 87

Step 3:
When dividing 393 by 87, we get 4 with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 45 after subtracting 348 from 393.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 87

Moving on to step 4:
If we divide 456 by 87, we get 5 and a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 435 away from 456, we end up with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 87

Step 5:
If we divide 217 by 87, we get 2 and a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
Subtracting 174 from 217 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 87

Step 6:
436 divided by 87 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 4525.0
Deduct 435 from 436 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 87, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4525.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
87 can be fit into 100 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 4525.01
Deduct 87 from 100 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
When dividing 130 by 87, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 4525.011
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 4525.011 with a remainder of 0.0043.
