We're dividing 49631242 by 687 
The aim is to understand the frequency of 687 in 49631242.

Going ahead to step 1:
If we divide 4 by 687, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 687

Advancing to step 2:
687 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 687

Moving on to step 3:
687 goes into 496 0 times with a remainder of 496.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 496 to get 496.
Include the next digit (3) from the dividend after 496, then repeat: 4963 / 687

On to step 4:
687 can be fit into 4963 7 times, resulting in a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 4809 from 4963 leaves us with 154.
Append the next digit (1) from the dividend to 154 and continue with: 1541 / 687

Going ahead to step 5:
1541 divided by 687 is 2 with a remainder of 167.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 1374 from 1541 to get 167.
Fetch the next digit (2) from the dividend, attach it to 167 and continue: 1672 / 687

Moving on to step 6:
687 goes into 1672 2 times with a remainder of 298.
The next digit of our result is 2. 
Result so far: 722.0
If we subtract 1374 from 1672, we get 298.
Include the next digit (4) from the dividend after 298, then repeat: 2984 / 687

On to step 7:
687 goes into 2984 4 times with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 7224.0
If we take 2748 away from 2984, we end up with 236.
Fetch the next digit (2) from the dividend, attach it to 236 and continue: 2362 / 687

Going ahead to step 8:
687 goes into 2362 3 times with a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 72243.0
If we take 2061 away from 2362, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 9:
If we divide 3010 by 687, we get 4 and a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 72243.4
Deduct 2748 from 3010 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
687 goes into 2620 3 times with a remainder of 559.
Put 3 as the next digit of the answer. 
Result so far: 72243.43
Subtract 2061 from 2620 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Let's proceed to step 11:
The number 687 fits into 5590 8 times, leaving a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 72243.438
Subtracting 5496 from 5590 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 12:
When dividing 940 by 687, we get 1 with a remainder of 253.
Use 1 as the next digit of our solution. 
Result so far: 72243.4381
Subtract 687 from 940 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 13:
When dividing 2530 by 687, we get 3 with a remainder of 469.
Write down 3 as next digit of the result. 
Result so far: 72243.43813
Deduct 2061 from 2530 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 14:
687 goes into 4690 6 times with a remainder of 568.
The number 6 becomes the next digit in our result. 
Result so far: 72243.438136
Deduct 4122 from 4690 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 15:
If we divide 5680 by 687, we get 8 and a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 72243.4381368
If we take 5496 away from 5680, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 16:
If we divide 1840 by 687, we get 2 and a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 72243.43813682
If we subtract 1374 from 1840, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Our division results in 72243.43813682 with a remaining 4.66e-07.
