71480925 ÷ 880 
The aim is to understand the frequency of 880 in 71480925.

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
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 880

Step 2:
880 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 880

Let's proceed to step 3:
If we divide 714 by 880, we get 0 and a remainder of 714.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 714 leaves us with 714.
Fetch the next digit (8) from the dividend, attach it to 714 and continue: 7148 / 880

Advancing to step 4:
880 can be fit into 7148 8 times, resulting in a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7040 away from 7148, we end up with 108.
Append the next digit (0) from the dividend to 108 and continue with: 1080 / 880

Moving on to step 5:
880 goes into 1080 1 times with a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 880 from 1080 leaves us with 200.
Bring next digit (9) of the dividend behind the 200 and repeat the process: 2009 / 880

Advancing to step 6:
880 can be fit into 2009 2 times, resulting in a remainder of 249.
Write down 2 as next digit of the result. 
Result so far: 812.0
The remainder is 249 after subtracting 1760 from 2009.
Bring next digit (2) of the dividend behind the 249 and repeat the process: 2492 / 880

Let's proceed to step 7:
880 can be fit into 2492 2 times, resulting in a remainder of 732.
Put 2 as the next digit of the answer. 
Result so far: 8122.0
Deduct 1760 from 2492 and we're left with 732.
Include the next digit (5) from the dividend after 732, then repeat: 7325 / 880

On to step 8:
The number 880 fits into 7325 8 times, leaving a remainder of 285.
Put 8 as the next digit of the answer. 
Result so far: 81228.0
Deduct 7040 from 7325 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 9:
The number 880 fits into 2850 3 times, leaving a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 81228.3
The remainder is 210 after subtracting 2640 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
880 can be fit into 2100 2 times, resulting in a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 81228.32
If we take 1760 away from 2100, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
880 can be fit into 3400 3 times, resulting in a remainder of 760.
Use 3 as the next digit of our solution. 
Result so far: 81228.323
Deduct 2640 from 3400 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 12:
880 can be fit into 7600 8 times, resulting in a remainder of 560.
The next digit of our result is 8. 
Result so far: 81228.3238
Deduct 7040 from 7600 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
The number 880 fits into 5600 6 times, leaving a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 81228.32386
The remainder is 320 after subtracting 5280 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
3200 divided by 880 is 3 with a remainder of 560.
Record the quotient 3 as the next digit in the result. 
Result so far: 81228.323863
If we subtract 2640 from 3200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
880 goes into 5600 6 times with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 81228.3238636
The remainder is 320 after subtracting 5280 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
If we divide 3200 by 880, we get 3 and a remainder of 560.
Record the quotient 3 as the next digit in the result. 
Result so far: 81228.32386363
Deduct 2640 from 3200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 81228.32386363 with a remainder of 5.6e-07.
