435126 ÷ 57 
The aim is to understand the frequency of 57 in 435126.

Moving on to step 1:
If we divide 4 by 57, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 57

Going ahead to step 2:
If we divide 43 by 57, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 57

On to step 3:
57 goes into 435 7 times with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 399 from 435, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 57

Moving on to step 4:
If we divide 361 by 57, we get 6 and a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 342 from 361 to get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 57

Moving on to step 5:
When dividing 192 by 57, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 763.0
Subtracting 171 from 192 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 57

On to step 6:
The number 57 fits into 216 3 times, leaving a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 7633.0
The remainder is 45 after subtracting 171 from 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
When dividing 450 by 57, we get 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 7633.7
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 7633.78
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
If we divide 540 by 57, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 7633.789
The remainder is 27 after subtracting 513 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
57 goes into 270 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 7633.7894
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 7633.78947
Subtracting 399 from 420 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
57 can be fit into 210 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 7633.789473
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
57 can be fit into 390 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7633.7894736
The remainder is 48 after subtracting 342 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 57, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 7633.78947368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 7633.78947368, and the remainder is 2.4e-08.
