We divide 53453437 by 435
The aim is to understand the frequency of 435 in 53453437.

On to step 1:
If we divide 5 by 435, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 435

On to step 2:
When dividing 53 by 435, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 435

Going ahead to step 3:
The number 435 fits into 534 1 times, leaving a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 435 from 534 and we're left with 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 435

On to step 4:
If we divide 995 by 435, we get 2 and a remainder of 125.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 870 from 995 leaves us with 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 435

Let's proceed to step 5:
If we divide 1253 by 435, we get 2 and a remainder of 383.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 870 from 1253 to get 383.
Take the next digit (4) from the dividend and append it to 383, then repeat: 3834 / 435

Moving on to step 6:
The number 435 fits into 3834 8 times, leaving a remainder of 354.
The number 8 becomes the next digit in our result. 
Result so far: 1228.0
Deduct 3480 from 3834 and we're left with 354.
Fetch the next digit (3) from the dividend, attach it to 354 and continue: 3543 / 435

Advancing to step 7:
435 goes into 3543 8 times with a remainder of 63.
The next digit of our result is 8. 
Result so far: 12288.0
The remainder is 63 after subtracting 3480 from 3543.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 435

Going ahead to step 8:
637 divided by 435 is 1 with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 122881.0
Subtracting 435 from 637 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
If we divide 2020 by 435, we get 4 and a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 122881.4
Subtract 1740 from 2020 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
435 goes into 2800 6 times with a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 122881.46
If we subtract 2610 from 2800, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
435 can be fit into 1900 4 times, resulting in a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 122881.464
Deduct 1740 from 1900 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
The number 435 fits into 1600 3 times, leaving a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 122881.4643
The remainder is 295 after subtracting 1305 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 13:
When dividing 2950 by 435, we get 6 with a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 122881.46436
Subtracting 2610 from 2950 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
If we divide 3400 by 435, we get 7 and a remainder of 355.
Write down 7 as next digit of the result. 
Result so far: 122881.464367
Deduct 3045 from 3400 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 15:
If we divide 3550 by 435, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 122881.4643678
Subtracting 3480 from 3550 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
The number 435 fits into 700 1 times, leaving a remainder of 265.
Use 1 as the next digit of our solution. 
Result so far: 122881.46436781
Deduct 435 from 700 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final result is 122881.46436781 with a remainder of 2.65e-07.
