We divide 17701906 by 880
The aim is to understand the frequency of 880 in 17701906.

Advancing to step 1:
The number 880 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 880

On to step 2:
When dividing 17 by 880, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 880

Moving on to step 3:
The number 880 fits into 177 0 times, leaving a remainder of 177.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 177 and we're left with 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 880

Advancing to step 4:
1770 divided by 880 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1760 from 1770 leaves us with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 880

Moving on to step 5:
880 goes into 101 0 times with a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 101 to get 101.
Fetch the next digit (9) from the dividend, attach it to 101 and continue: 1019 / 880

Step 6:
880 can be fit into 1019 1 times, resulting in a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we subtract 880 from 1019, we get 139.
Append the next digit (0) from the dividend to 139 and continue with: 1390 / 880

Let's proceed to step 7:
880 goes into 1390 1 times with a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 2011.0
Subtract 880 from 1390 to get 510.
Append the next digit (6) from the dividend to 510 and continue with: 5106 / 880

On to step 8:
880 can be fit into 5106 5 times, resulting in a remainder of 706.
Record the quotient 5 as the next digit in the result. 
Result so far: 20115.0
Deduct 4400 from 5106 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 9:
If we divide 7060 by 880, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 20115.8
Deduct 7040 from 7060 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
880 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 20115.8
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
880 goes into 2000 2 times with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 20115.802
The remainder is 240 after subtracting 1760 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
If we divide 2400 by 880, we get 2 and a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 20115.8022
Deduct 1760 from 2400 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 20115.8022 with a remainder of 0.0064.
