19610228 ÷ 87 
The aim is to understand the frequency of 87 in 19610228.

Going ahead to step 1:
1 divided by 87 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 87

Step 2:
The number 87 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 87

On to step 3:
196 divided by 87 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 174 from 196 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 87

Moving on to step 4:
The number 87 fits into 221 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 174 from 221 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 87

Step 5:
When dividing 470 by 87, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Deduct 435 from 470 and we're left with 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 87

Let's proceed to step 6:
87 can be fit into 352 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 2254.0
Deduct 348 from 352 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 87

Going ahead to step 7:
If we divide 42 by 87, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 22540.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 87

Let's proceed to step 8:
When dividing 428 by 87, we get 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 225404.0
If we take 348 away from 428, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
87 goes into 800 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 225404.9
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
87 can be fit into 170 1 times, resulting in a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 225404.91
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 225404.919
If we subtract 783 from 830, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
87 goes into 470 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 225404.9195
Subtracting 435 from 470 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
When dividing 350 by 87, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 225404.91954
Subtracting 348 from 350 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
If we divide 20 by 87, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 225404.91954
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
If we divide 200 by 87, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 225404.9195402
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 16:
If we divide 260 by 87, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 225404.91954022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 225404.91954022 with a remaining 8.6e-08.
