71003102 divided by 880 
The aim is to understand the frequency of 880 in 71003102.

Let's proceed to step 1:
880 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 880

Advancing to step 2:
880 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 880

On to step 3:
880 goes into 710 0 times with a remainder of 710.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 710, we end up with 710.
Include the next digit (0) from the dividend after 710, then repeat: 7100 / 880

On to step 4:
If we divide 7100 by 880, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7040 from 7100 to get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 880

Moving on to step 5:
880 goes into 603 0 times with a remainder of 603.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtract 0 from 603 to get 603.
Fetch the next digit (1) from the dividend, attach it to 603 and continue: 6031 / 880

Moving on to step 6:
6031 divided by 880 is 6 with a remainder of 751.
Record the quotient 6 as the next digit in the result. 
Result so far: 806.0
Deduct 5280 from 6031 and we're left with 751.
Take the next digit (0) from the dividend and append it to 751, then repeat: 7510 / 880

Going ahead to step 7:
880 can be fit into 7510 8 times, resulting in a remainder of 470.
Record the quotient 8 as the next digit in the result. 
Result so far: 8068.0
The remainder is 470 after subtracting 7040 from 7510.
Grab the next digit (2) from the dividend, add it to 470, then carry on: 4702 / 880

Moving on to step 8:
The number 880 fits into 4702 5 times, leaving a remainder of 302.
Use 5 as the next digit of our solution. 
Result so far: 80685.0
The remainder is 302 after subtracting 4400 from 4702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
880 goes into 3020 3 times with a remainder of 380.
Record the quotient 3 as the next digit in the result. 
Result so far: 80685.3
If we subtract 2640 from 3020, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
3800 divided by 880 is 4 with a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 80685.34
If we subtract 3520 from 3800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
The number 880 fits into 2800 3 times, leaving a remainder of 160.
The number 3 becomes the next digit in our result. 
Result so far: 80685.343
If we take 2640 away from 2800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
880 can be fit into 1600 1 times, resulting in a remainder of 720.
The next digit of our result is 1. 
Result so far: 80685.3431
If we take 880 away from 1600, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 13:
If we divide 7200 by 880, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 80685.34318
Deduct 7040 from 7200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
1600 divided by 880 is 1 with a remainder of 720.
The next digit of our result is 1. 
Result so far: 80685.343181
The remainder is 720 after subtracting 880 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 15:
880 goes into 7200 8 times with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 80685.3431818
Deduct 7040 from 7200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 880 fits into 1600 1 times, leaving a remainder of 720.
The next digit of our result is 1. 
Result so far: 80685.34318181
The remainder is 720 after subtracting 880 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final outcome is 80685.34318181, with a leftover of 7.2e-07.
