We divide 36631319 by 687
The aim is to understand the frequency of 687 in 36631319.

Step 1:
687 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 687

Step 2:
When dividing 36 by 687, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 687

Advancing to step 3:
687 goes into 366 0 times with a remainder of 366.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 366, we end up with 366.
Bring next digit (3) of the dividend behind the 366 and repeat the process: 3663 / 687

Moving on to step 4:
687 can be fit into 3663 5 times, resulting in a remainder of 228.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 3435 from 3663 to get 228.
Take the next digit (1) from the dividend and append it to 228, then repeat: 2281 / 687

Going ahead to step 5:
687 can be fit into 2281 3 times, resulting in a remainder of 220.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 2061 from 2281 and we're left with 220.
Fetch the next digit (3) from the dividend, attach it to 220 and continue: 2203 / 687

Step 6:
2203 divided by 687 is 3 with a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 533.0
If we subtract 2061 from 2203, we get 142.
Bring next digit (1) of the dividend behind the 142 and repeat the process: 1421 / 687

Going ahead to step 7:
687 can be fit into 1421 2 times, resulting in a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 5332.0
If we take 1374 away from 1421, we end up with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 687

Going ahead to step 8:
479 divided by 687 is 0 with a remainder of 479.
The next digit of our result is 0. 
Result so far: 53320.0
The remainder is 479 after subtracting 0 from 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 9:
687 can be fit into 4790 6 times, resulting in a remainder of 668.
Use 6 as the next digit of our solution. 
Result so far: 53320.6
Deduct 4122 from 4790 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Step 10:
The number 687 fits into 6680 9 times, leaving a remainder of 497.
The number 9 becomes the next digit in our result. 
Result so far: 53320.69
If we subtract 6183 from 6680, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 11:
When dividing 4970 by 687, we get 7 with a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 53320.697
If we take 4809 away from 4970, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 12:
687 goes into 1610 2 times with a remainder of 236.
The next digit of our result is 2. 
Result so far: 53320.6972
Subtract 1374 from 1610 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 13:
2360 divided by 687 is 3 with a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 53320.69723
If we take 2061 away from 2360, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 14:
The number 687 fits into 2990 4 times, leaving a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 53320.697234
If we subtract 2748 from 2990, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 15:
If we divide 2420 by 687, we get 3 and a remainder of 359.
The next digit of our result is 3. 
Result so far: 53320.6972343
If we take 2061 away from 2420, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 16:
When dividing 3590 by 687, we get 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 53320.69723435
If we take 3435 away from 3590, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 53320.69723435, and the remainder is 1.55e-07.
