Let's divide 601861 by 87
The aim is to understand the frequency of 87 in 601861.

Going ahead to step 1:
87 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 87

Going ahead to step 2:
60 divided by 87 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 87

Moving on to step 3:
When dividing 601 by 87, we get 6 with a remainder of 79.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 522 from 601, we get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 87

Advancing to step 4:
When dividing 798 by 87, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
The remainder is 15 after subtracting 783 from 798.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 87

Advancing to step 5:
The number 87 fits into 156 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 691.0
Subtracting 87 from 156 leaves us with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 87

Step 6:
The number 87 fits into 691 7 times, leaving a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 6917.0
If we take 609 away from 691, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
If we divide 820 by 87, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 6917.9
Subtracting 783 from 820 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
370 divided by 87 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 6917.94
Subtracting 348 from 370 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
87 goes into 220 2 times with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 6917.942
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
If we divide 460 by 87, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6917.9425
Subtracting 435 from 460 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
The number 87 fits into 250 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 6917.94252
Subtract 174 from 250 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
87 goes into 760 8 times with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 6917.942528
Deduct 696 from 760 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
87 can be fit into 640 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 6917.9425287
If we subtract 609 from 640, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
87 goes into 310 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 6917.94252873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 6917.94252873 and a remainder of 4.9e-08.
