We divide 661318 by 87
The aim is to understand the frequency of 87 in 661318.

On to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 87

On to step 2:
When dividing 66 by 87, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 87

Advancing to step 3:
87 goes into 661 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 609 from 661 leaves us with 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 87

Moving on to step 4:
If we divide 523 by 87, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we take 522 away from 523, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 87

Step 5:
11 divided by 87 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 760.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 87

Going ahead to step 6:
87 can be fit into 118 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 7601.0
Subtract 87 from 118 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 87 fits into 310 3 times, leaving a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 7601.3
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
The number 87 fits into 490 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7601.35
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 7601.356
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
87 goes into 280 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 7601.3563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
190 divided by 87 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 7601.35632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
87 can be fit into 160 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 7601.356321
Deduct 87 from 160 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
If we divide 730 by 87, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 7601.3563218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
87 can be fit into 340 3 times, resulting in a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 7601.35632183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 7601.35632183 with a remaining 7.9e-08.
