We're dividing 53639984 by 957 
The aim is to understand the frequency of 957 in 53639984.

Step 1:
The number 957 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 957

Step 2:
If we divide 53 by 957, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 957

Step 3:
957 goes into 536 0 times with a remainder of 536.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 536, we end up with 536.
Bring next digit (3) of the dividend behind the 536 and repeat the process: 5363 / 957

Moving on to step 4:
When dividing 5363 by 957, we get 5 with a remainder of 578.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4785 from 5363, we get 578.
Take the next digit (9) from the dividend and append it to 578, then repeat: 5789 / 957

Moving on to step 5:
957 can be fit into 5789 6 times, resulting in a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 5742 from 5789 to get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 957

Let's proceed to step 6:
479 divided by 957 is 0 with a remainder of 479.
The number 0 becomes the next digit in our result. 
Result so far: 560.0
Deduct 0 from 479 and we're left with 479.
Include the next digit (8) from the dividend after 479, then repeat: 4798 / 957

Going ahead to step 7:
The number 957 fits into 4798 5 times, leaving a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 5605.0
Subtract 4785 from 4798 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 957

On to step 8:
957 can be fit into 134 0 times, resulting in a remainder of 134.
The number 0 becomes the next digit in our result. 
Result so far: 56050.0
Deduct 0 from 134 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 9:
957 can be fit into 1340 1 times, resulting in a remainder of 383.
Record the quotient 1 as the next digit in the result. 
Result so far: 56050.1
The remainder is 383 after subtracting 957 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 10:
The number 957 fits into 3830 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 56050.14
The remainder is 2 after subtracting 3828 from 3830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
957 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 56050.14
If we take 0 away from 20, we end up 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.

Let's proceed to step 12:
957 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 56050.14
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 56050.14, and the remainder is 0.002.
