Let's divide 78353455 by 880
The aim is to understand the frequency of 880 in 78353455.

Moving on to step 1:
If we divide 7 by 880, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 880

Moving on to step 2:
If we divide 78 by 880, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 880

Step 3:
When dividing 783 by 880, we get 0 with a remainder of 783.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 783, we get 783.
Include the next digit (5) from the dividend after 783, then repeat: 7835 / 880

On to step 4:
880 can be fit into 7835 8 times, resulting in a remainder of 795.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7040 from 7835, we get 795.
Bring next digit (3) of the dividend behind the 795 and repeat the process: 7953 / 880

Advancing to step 5:
7953 divided by 880 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 7920 from 7953, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 880

Advancing to step 6:
When dividing 334 by 880, we get 0 with a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
Deduct 0 from 334 and we're left with 334.
Take the next digit (5) from the dividend and append it to 334, then repeat: 3345 / 880

Moving on to step 7:
3345 divided by 880 is 3 with a remainder of 705.
Use 3 as the next digit of our solution. 
Result so far: 8903.0
If we subtract 2640 from 3345, we get 705.
Bring next digit (5) of the dividend behind the 705 and repeat the process: 7055 / 880

On to step 8:
When dividing 7055 by 880, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 89038.0
The remainder is 15 after subtracting 7040 from 7055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
If we divide 150 by 880, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 89038.0
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
880 goes into 1500 1 times with a remainder of 620.
Put 1 as the next digit of the answer. 
Result so far: 89038.01
If we take 880 away from 1500, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
880 goes into 6200 7 times with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 89038.017
Subtract 6160 from 6200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 880 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 89038.017
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
880 can be fit into 4000 4 times, resulting in a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 89038.01704
Subtracting 3520 from 4000 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
When dividing 4800 by 880, we get 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 89038.017045
Subtract 4400 from 4800 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
880 can be fit into 4000 4 times, resulting in a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 89038.0170454
If we subtract 3520 from 4000, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
4800 divided by 880 is 5 with a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 89038.01704545
The remainder is 400 after subtracting 4400 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 89038.01704545 and a remainder of 4e-07.
