We're dividing 291908 by 87 
The aim is to understand the frequency of 87 in 291908.

Advancing to step 1:
When dividing 2 by 87, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 87

Moving on to step 2:
29 divided by 87 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 87

Advancing to step 3:
87 can be fit into 291 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 261 from 291, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 87

Going ahead to step 4:
The number 87 fits into 309 3 times, leaving a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 261 away from 309, we end up with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 87

Going ahead to step 5:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 335.0
Subtracting 435 from 480 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 87

On to step 6:
87 can be fit into 458 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 3355.0
The remainder is 23 after subtracting 435 from 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
87 can be fit into 230 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 3355.2
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
87 goes into 560 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 3355.26
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
87 can be fit into 380 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 3355.264
The remainder is 32 after subtracting 348 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 87, we get 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 3355.2643
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
If we divide 590 by 87, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 3355.26436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
When dividing 680 by 87, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 3355.264367
If we subtract 609 from 680, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 13:
When dividing 710 by 87, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 3355.2643678
Subtract 696 from 710 to 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 14:
87 goes into 140 1 times with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 3355.26436781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 3355.26436781, and the remainder is 5.3e-08.
