We're dividing 616379 by 87 
The aim is to understand the frequency of 87 in 616379.

Step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 87

Step 2:
If we divide 61 by 87, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 87

Advancing to step 3:
87 goes into 616 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 609 from 616 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 87

Going ahead to step 4:
73 divided by 87 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 73 after subtracting 0 from 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 87

Step 5:
87 goes into 737 8 times with a remainder of 41.
The next digit of our result is 8. 
Result so far: 708.0
Subtracting 696 from 737 leaves us with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 87

Going ahead to step 6:
When dividing 419 by 87, we get 4 with a remainder of 71.
The next digit of our result is 4. 
Result so far: 7084.0
Deduct 348 from 419 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
87 goes into 710 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 7084.8
If we subtract 696 from 710, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 87 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 7084.81
If we subtract 87 from 140, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
If we divide 530 by 87, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7084.816
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 87 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7084.816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
800 divided by 87 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 7084.81609
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
170 divided by 87 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 7084.816091
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 13:
87 goes into 830 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 7084.8160919
Subtracting 783 from 830 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
87 goes into 470 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7084.81609195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 7084.81609195 and a remainder of 3.5e-08.
