43012078 ÷ 587 
The aim is to understand the frequency of 587 in 43012078.

Going ahead to step 1:
4 divided by 587 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 587

Let's proceed to step 2:
If we divide 43 by 587, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 587

Let's proceed to step 3:
587 goes into 430 0 times with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 430 and we're left with 430.
Append the next digit (1) from the dividend to 430 and continue with: 4301 / 587

Moving on to step 4:
4301 divided by 587 is 7 with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 4109 away from 4301, we end up with 192.
Take the next digit (2) from the dividend and append it to 192, then repeat: 1922 / 587

Moving on to step 5:
The number 587 fits into 1922 3 times, leaving a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 1761 from 1922 leaves us with 161.
Fetch the next digit (0) from the dividend, attach it to 161 and continue: 1610 / 587

Moving on to step 6:
1610 divided by 587 is 2 with a remainder of 436.
Record the quotient 2 as the next digit in the result. 
Result so far: 732.0
The remainder is 436 after subtracting 1174 from 1610.
Bring next digit (7) of the dividend behind the 436 and repeat the process: 4367 / 587

On to step 7:
587 goes into 4367 7 times with a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 7327.0
Deduct 4109 from 4367 and we're left with 258.
Append the next digit (8) from the dividend to 258 and continue with: 2588 / 587

Advancing to step 8:
2588 divided by 587 is 4 with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 73274.0
Subtracting 2348 from 2588 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 9:
The number 587 fits into 2400 4 times, leaving a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 73274.4
Deduct 2348 from 2400 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.

Let's proceed to step 10:
When dividing 520 by 587, we get 0 with a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 73274.4
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 11:
The number 587 fits into 5200 8 times, leaving a remainder of 504.
The number 8 becomes the next digit in our result. 
Result so far: 73274.408
Deduct 4696 from 5200 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 12:
When dividing 5040 by 587, we get 8 with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 73274.4088
Subtract 4696 from 5040 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 73274.4088 and a remainder of 0.00344.
