We divide 140106 by 87
The aim is to understand the frequency of 87 in 140106.

On to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 87

Moving on to step 2:
The number 87 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 87

Going ahead to step 3:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 87 from 140, we get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 87

Moving on to step 4:
When dividing 531 by 87, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 522 from 531 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 87

Step 5:
If we divide 90 by 87, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we subtract 87 from 90, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 87

Going ahead to step 6:
If we divide 36 by 87, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 1610.0
The remainder is 36 after subtracting 0 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
360 divided by 87 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1610.4
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
87 can be fit into 120 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1610.41
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
The number 87 fits into 330 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 1610.413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
When dividing 690 by 87, we get 7 with a remainder of 81.
The next digit of our result is 7. 
Result so far: 1610.4137
The remainder is 81 after subtracting 609 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
If we divide 810 by 87, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 1610.41379
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
87 can be fit into 270 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 1610.413793
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1610.4137931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1610.4137931
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 1610.4137931 and a remainder of 3e-08.
