60867999 ÷ 87 
The aim is to understand the frequency of 87 in 60867999.

Advancing to step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 87

Moving on to step 2:
If we divide 60 by 87, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 87

Moving on to step 3:
87 goes into 608 6 times with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 522 from 608, we get 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 87

Step 4:
The number 87 fits into 866 9 times, leaving a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtracting 783 from 866 leaves us with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 87

On to step 5:
When dividing 837 by 87, we get 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 699.0
Subtract 783 from 837 to get 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 87

Advancing to step 6:
When dividing 549 by 87, we get 6 with a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 6996.0
Subtracting 522 from 549 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 87

Going ahead to step 7:
If we divide 279 by 87, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 69963.0
The remainder is 18 after subtracting 261 from 279.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 87

Moving on to step 8:
189 divided by 87 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 699632.0
If we take 174 away from 189, we end up 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.

Step 9:
87 goes into 150 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 699632.1
The remainder is 63 after subtracting 87 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
87 goes into 630 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 699632.17
Subtracting 609 from 630 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
210 divided by 87 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 699632.172
If we subtract 174 from 210, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
87 goes into 360 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 699632.1724
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
If we divide 120 by 87, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 699632.17241
If we take 87 away from 120, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 699632.172413
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.

On to step 15:
87 can be fit into 690 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 699632.1724137
Deduct 609 from 690 and we're left with 81.
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 16:
If we divide 810 by 87, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 699632.17241379
Subtracting 783 from 810 leaves us 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.

After the division, we end up with 699632.17241379 and a remainder of 2.7e-08.
