We divide 15990909 by 928
The aim is to understand the frequency of 928 in 15990909.

Moving on to step 1:
If we divide 1 by 928, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 928

Step 2:
If we divide 15 by 928, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 928

Going ahead to step 3:
If we divide 159 by 928, we get 0 and a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 928

Moving on to step 4:
928 can be fit into 1599 1 times, resulting in a remainder of 671.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 928 from 1599 and we're left with 671.
Fetch the next digit (0) from the dividend, attach it to 671 and continue: 6710 / 928

Going ahead to step 5:
6710 divided by 928 is 7 with a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 6496 from 6710, we get 214.
Include the next digit (9) from the dividend after 214, then repeat: 2149 / 928

Advancing to step 6:
928 goes into 2149 2 times with a remainder of 293.
Write down 2 as next digit of the result. 
Result so far: 172.0
Deduct 1856 from 2149 and we're left with 293.
Append the next digit (0) from the dividend to 293 and continue with: 2930 / 928

Going ahead to step 7:
2930 divided by 928 is 3 with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 1723.0
If we subtract 2784 from 2930, we get 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 928

Advancing to step 8:
928 can be fit into 1469 1 times, resulting in a remainder of 541.
Record the quotient 1 as the next digit in the result. 
Result so far: 17231.0
Deduct 928 from 1469 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 9:
5410 divided by 928 is 5 with a remainder of 770.
Record the quotient 5 as the next digit in the result. 
Result so far: 17231.5
If we subtract 4640 from 5410, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 10:
When dividing 7700 by 928, we get 8 with a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 17231.58
The remainder is 276 after subtracting 7424 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
When dividing 2760 by 928, we get 2 with a remainder of 904.
Put 2 as the next digit of the answer. 
Result so far: 17231.582
The remainder is 904 after subtracting 1856 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Moving on to step 12:
928 can be fit into 9040 9 times, resulting in a remainder of 688.
The number 9 becomes the next digit in our result. 
Result so far: 17231.5829
If we subtract 8352 from 9040, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 13:
928 goes into 6880 7 times with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 17231.58297
Subtracting 6496 from 6880 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 14:
3840 divided by 928 is 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 17231.582974
Subtracting 3712 from 3840 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
If we divide 1280 by 928, we get 1 and a remainder of 352.
The next digit of our result is 1. 
Result so far: 17231.5829741
Deduct 928 from 1280 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 16:
The number 928 fits into 3520 3 times, leaving a remainder of 736.
Record the quotient 3 as the next digit in the result. 
Result so far: 17231.58297413
Subtracting 2784 from 3520 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The quotient of the division is 17231.58297413, and the remainder is 7.36e-07.
