We're dividing 19860748 by 964 
The aim is to understand the frequency of 964 in 19860748.

On to step 1:
1 divided by 964 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 964

Moving on to step 2:
964 goes into 19 0 times 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.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 964

Moving on to step 3:
When dividing 198 by 964, we get 0 with a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Bring next digit (6) of the dividend behind the 198 and repeat the process: 1986 / 964

On to step 4:
964 can be fit into 1986 2 times, resulting in a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1928 away from 1986, we end up with 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 964

Advancing to step 5:
580 divided by 964 is 0 with a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 580 after subtracting 0 from 580.
Take the next digit (7) from the dividend and append it to 580, then repeat: 5807 / 964

Moving on to step 6:
964 can be fit into 5807 6 times, resulting in a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 206.0
If we take 5784 away from 5807, we end up with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 964

On to step 7:
If we divide 234 by 964, we get 0 and a remainder of 234.
Record the quotient 0 as the next digit in the result. 
Result so far: 2060.0
If we subtract 0 from 234, we get 234.
Bring next digit (8) of the dividend behind the 234 and repeat the process: 2348 / 964

Let's proceed to step 8:
The number 964 fits into 2348 2 times, leaving a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 20602.0
Subtracting 1928 from 2348 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 9:
When dividing 4200 by 964, we get 4 with a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 20602.4
Deduct 3856 from 4200 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 10:
When dividing 3440 by 964, we get 3 with a remainder of 548.
Put 3 as the next digit of the answer. 
Result so far: 20602.43
Subtracting 2892 from 3440 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 11:
If we divide 5480 by 964, we get 5 and a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 20602.435
If we take 4820 away from 5480, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 12:
6600 divided by 964 is 6 with a remainder of 816.
Use 6 as the next digit of our solution. 
Result so far: 20602.4356
Deduct 5784 from 6600 and we're left with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 13:
When dividing 8160 by 964, we get 8 with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 20602.43568
The remainder is 448 after subtracting 7712 from 8160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 14:
964 can be fit into 4480 4 times, resulting in a remainder of 624.
Write down 4 as next digit of the result. 
Result so far: 20602.435684
Deduct 3856 from 4480 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Moving on to step 15:
If we divide 6240 by 964, we get 6 and a remainder of 456.
Put 6 as the next digit of the answer. 
Result so far: 20602.4356846
If we subtract 5784 from 6240, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 16:
The number 964 fits into 4560 4 times, leaving a remainder of 704.
Put 4 as the next digit of the answer. 
Result so far: 20602.43568464
If we subtract 3856 from 4560, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final outcome is 20602.43568464, with a leftover of 7.04e-07.
