7890337 ÷ 775 
The aim is to understand the frequency of 775 in 7890337.

Moving on to step 1:
If we divide 7 by 775, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 775

Let's proceed to step 2:
775 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 775

On to step 3:
When dividing 789 by 775, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 775 from 789 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 775

Let's proceed to step 4:
775 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 140 and we're left with 140.
Fetch the next digit (3) from the dividend, attach it to 140 and continue: 1403 / 775

On to step 5:
775 goes into 1403 1 times with a remainder of 628.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we subtract 775 from 1403, we get 628.
Bring next digit (3) of the dividend behind the 628 and repeat the process: 6283 / 775

Let's proceed to step 6:
The number 775 fits into 6283 8 times, leaving a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 1018.0
The remainder is 83 after subtracting 6200 from 6283.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 775

Step 7:
837 divided by 775 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 10181.0
If we subtract 775 from 837, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
620 divided by 775 is 0 with a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 10181.0
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 9:
The number 775 fits into 6200 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 10181.08
Subtract 6200 from 6200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
775 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10181.08
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 775 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10181.08
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10181.08 with a remainder of 0.0.
