19015669 ÷ 964 
The aim is to understand the frequency of 964 in 19015669.

On to step 1:
964 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 964

Moving on to step 2:
19 divided by 964 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 964

Moving on to step 3:
When dividing 190 by 964, we get 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 190 after subtracting 0 from 190.
Include the next digit (1) from the dividend after 190, then repeat: 1901 / 964

Let's proceed to step 4:
1901 divided by 964 is 1 with a remainder of 937.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 964 away from 1901, we end up with 937.
Append the next digit (5) from the dividend to 937 and continue with: 9375 / 964

Advancing to step 5:
The number 964 fits into 9375 9 times, leaving a remainder of 699.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 8676 from 9375, we get 699.
Grab the next digit (6) from the dividend, add it to 699, then carry on: 6996 / 964

Moving on to step 6:
The number 964 fits into 6996 7 times, leaving a remainder of 248.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we take 6748 away from 6996, we end up with 248.
Bring next digit (6) of the dividend behind the 248 and repeat the process: 2486 / 964

Going ahead to step 7:
964 can be fit into 2486 2 times, resulting in a remainder of 558.
Write down 2 as next digit of the result. 
Result so far: 1972.0
Deduct 1928 from 2486 and we're left with 558.
Bring next digit (9) of the dividend behind the 558 and repeat the process: 5589 / 964

Going ahead to step 8:
5589 divided by 964 is 5 with a remainder of 769.
The next digit of our result is 5. 
Result so far: 19725.0
If we subtract 4820 from 5589, we get 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Let's proceed to step 9:
964 goes into 7690 7 times with a remainder of 942.
The next digit of our result is 7. 
Result so far: 19725.7
The remainder is 942 after subtracting 6748 from 7690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9420, and continue the process.

Let's proceed to step 10:
964 goes into 9420 9 times with a remainder of 744.
The next digit of our result is 9. 
Result so far: 19725.79
Subtracting 8676 from 9420 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 11:
7440 divided by 964 is 7 with a remainder of 692.
Put 7 as the next digit of the answer. 
Result so far: 19725.797
Subtracting 6748 from 7440 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

On to step 12:
If we divide 6920 by 964, we get 7 and a remainder of 172.
The next digit of our result is 7. 
Result so far: 19725.7977
If we take 6748 away from 6920, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 19725.7977, with a leftover of 0.00172.
