We divide 42640 by 76
The aim is to understand the frequency of 76 in 42640.

Let's proceed to step 1:
When dividing 4 by 76, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 76

Going ahead to step 2:
76 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 76

Let's proceed to step 3:
76 can be fit into 426 5 times, resulting in a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 380 from 426 and we're left with 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 76

On to step 4:
76 can be fit into 464 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 456 from 464 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 76

Advancing to step 5:
If we divide 80 by 76, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 561.0
Subtracting 76 from 80 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
76 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 561.0
Subtracting 0 from 40 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.

Step 7:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 561.05
If we subtract 380 from 400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
76 can be fit into 200 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 561.052
Deduct 152 from 200 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
The number 76 fits into 480 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 561.0526
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 76 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 561.05263
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 76 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 561.052631
Subtract 76 from 120 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 76, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 561.0526315
Subtract 380 from 440 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
76 can be fit into 600 7 times, resulting in a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 561.05263157
Deduct 532 from 600 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 561.05263157 with a remainder of 6.8e-08.
