687691 divided by 48 
The aim is to understand the frequency of 48 in 687691.

Going ahead to step 1:
If we divide 6 by 48, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 48

Moving on to step 2:
48 goes into 68 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 48 from 68 and we're left with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 48

On to step 3:
If we divide 207 by 48, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 192 from 207 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 48

Moving on to step 4:
156 divided by 48 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
The remainder is 12 after subtracting 144 from 156.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 48

Step 5:
The number 48 fits into 129 2 times, leaving a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 1432.0
If we take 96 away from 129, we end up with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 48

On to step 6:
331 divided by 48 is 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 14326.0
Subtracting 288 from 331 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
48 goes into 430 8 times with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 14326.8
Deduct 384 from 430 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
When dividing 460 by 48, we get 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 14326.89
Deduct 432 from 460 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 9:
When dividing 280 by 48, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 14326.895
Subtracting 240 from 280 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 48 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 14326.8958
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 48 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 14326.89583
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 14326.895833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 14326.895833 with a remainder of 1.6e-06.
