3734232 ÷ 87 
The aim is to understand the frequency of 87 in 3734232.

Step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 87

Going ahead to step 2:
When dividing 37 by 87, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 87

Let's proceed to step 3:
When dividing 373 by 87, we get 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 348 away from 373, we end up with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 87

Going ahead to step 4:
87 goes into 254 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 174 from 254 leaves us with 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 87

Advancing to step 5:
The number 87 fits into 802 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
If we subtract 783 from 802, we get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 87

Going ahead to step 6:
When dividing 193 by 87, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 4292.0
If we take 174 away from 193, we end up with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 87

On to step 7:
The number 87 fits into 192 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42922.0
Subtracting 174 from 192 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 87 fits into 180 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 42922.2
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 87, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 42922.2
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
87 can be fit into 600 6 times, resulting in a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 42922.206
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
87 goes into 780 8 times with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 42922.2068
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
The number 87 fits into 840 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 42922.20689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 13:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 42922.206896
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
87 can be fit into 480 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 42922.2068965
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 15:
The number 87 fits into 450 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 42922.20689655
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 42922.20689655 and a remainder of 1.5e-08.
