We're dividing 37751749 by 680 
The aim is to understand the frequency of 680 in 37751749.

Advancing to step 1:
The number 680 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 680

Moving on to step 2:
If we divide 37 by 680, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 680

Moving on to step 3:
When dividing 377 by 680, we get 0 with a remainder of 377.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 377 leaves us with 377.
Bring next digit (5) of the dividend behind the 377 and repeat the process: 3775 / 680

On to step 4:
When dividing 3775 by 680, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 3400 from 3775 leaves us with 375.
Grab the next digit (1) from the dividend, add it to 375, then carry on: 3751 / 680

Moving on to step 5:
3751 divided by 680 is 5 with a remainder of 351.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 3400 from 3751 and we're left with 351.
Include the next digit (7) from the dividend after 351, then repeat: 3517 / 680

Step 6:
When dividing 3517 by 680, we get 5 with a remainder of 117.
Write down 5 as next digit of the result. 
Result so far: 555.0
Deduct 3400 from 3517 and we're left with 117.
Bring next digit (4) of the dividend behind the 117 and repeat the process: 1174 / 680

On to step 7:
680 can be fit into 1174 1 times, resulting in a remainder of 494.
Put 1 as the next digit of the answer. 
Result so far: 5551.0
If we take 680 away from 1174, we end up with 494.
Append the next digit (9) from the dividend to 494 and continue with: 4949 / 680

Advancing to step 8:
4949 divided by 680 is 7 with a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 55517.0
If we subtract 4760 from 4949, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 9:
680 goes into 1890 2 times with a remainder of 530.
The next digit of our result is 2. 
Result so far: 55517.2
If we subtract 1360 from 1890, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 10:
The number 680 fits into 5300 7 times, leaving a remainder of 540.
The number 7 becomes the next digit in our result. 
Result so far: 55517.27
Subtracting 4760 from 5300 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
5400 divided by 680 is 7 with a remainder of 640.
The number 7 becomes the next digit in our result. 
Result so far: 55517.277
Deduct 4760 from 5400 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 55517.277 with a remainder of 0.064.
