We divide 308641 by 87
The aim is to understand the frequency of 87 in 308641.

Moving on to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 87

On to step 2:
When dividing 30 by 87, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 87

On to step 3:
When dividing 308 by 87, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 261 away from 308, we end up with 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 87

On to step 4:
87 can be fit into 476 5 times, resulting in a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 41 after subtracting 435 from 476.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 87

Advancing to step 5:
87 goes into 414 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 354.0
If we subtract 348 from 414, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 87

Going ahead to step 6:
If we divide 661 by 87, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 3547.0
Deduct 609 from 661 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.

Moving on to step 7:
If we divide 520 by 87, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 3547.5
Subtracting 435 from 520 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
87 goes into 850 9 times with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 3547.59
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.

Step 9:
When dividing 670 by 87, we get 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 3547.597
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
87 goes into 610 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3547.5977
If we take 609 away from 610, we end up 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.

The quotient of the division is 3547.5977, and the remainder is 1e-05.
