437970 ÷ 53 
The aim is to understand the frequency of 53 in 437970.

Moving on to step 1:
When dividing 4 by 53, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 53

Advancing to step 2:
The number 53 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 53

On to step 3:
437 divided by 53 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 424 from 437 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 53

Going ahead to step 4:
139 divided by 53 is 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 106 from 139, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 53

Moving on to step 5:
The number 53 fits into 337 6 times, leaving a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
If we subtract 318 from 337, we get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 53

Advancing to step 6:
The number 53 fits into 190 3 times, leaving a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 8263.0
If we subtract 159 from 190, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
If we divide 310 by 53, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 8263.5
Subtract 265 from 310 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
53 can be fit into 450 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8263.58
If we subtract 424 from 450, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 53, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 8263.584
Subtracting 212 from 260 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
53 can be fit into 480 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8263.5849
Deduct 477 from 480 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 53 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8263.5849
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 53, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8263.584905
Deduct 265 from 300 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
53 can be fit into 350 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8263.5849056
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 53, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 8263.58490566
Deduct 318 from 320 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 8263.58490566, and the remainder is 2e-09.
