We're dividing 15607964 by 594 
The aim is to understand the frequency of 594 in 15607964.

Step 1:
The number 594 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 594

Moving on to step 2:
15 divided by 594 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 594

Moving on to step 3:
594 can be fit into 156 0 times, resulting in a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Take the next digit (0) from the dividend and append it to 156, then repeat: 1560 / 594

Moving on to step 4:
594 can be fit into 1560 2 times, resulting in a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1188 from 1560, we get 372.
Fetch the next digit (7) from the dividend, attach it to 372 and continue: 3727 / 594

Advancing to step 5:
3727 divided by 594 is 6 with a remainder of 163.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 3564 from 3727 and we're left with 163.
Include the next digit (9) from the dividend after 163, then repeat: 1639 / 594

Let's proceed to step 6:
594 goes into 1639 2 times with a remainder of 451.
Use 2 as the next digit of our solution. 
Result so far: 262.0
If we take 1188 away from 1639, we end up with 451.
Fetch the next digit (6) from the dividend, attach it to 451 and continue: 4516 / 594

Moving on to step 7:
594 goes into 4516 7 times with a remainder of 358.
The next digit of our result is 7. 
Result so far: 2627.0
If we take 4158 away from 4516, we end up with 358.
Bring next digit (4) of the dividend behind the 358 and repeat the process: 3584 / 594

On to step 8:
When dividing 3584 by 594, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 26276.0
Deduct 3564 from 3584 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.

Step 9:
The number 594 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 26276.0
Subtract 0 from 200 to get 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 10:
594 can be fit into 2000 3 times, resulting in a remainder of 218.
The number 3 becomes the next digit in our result. 
Result so far: 26276.03
If we subtract 1782 from 2000, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
2180 divided by 594 is 3 with a remainder of 398.
The number 3 becomes the next digit in our result. 
Result so far: 26276.033
If we take 1782 away from 2180, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final outcome is 26276.033, with a leftover of 0.0398.
