31422939 ÷ 435 
The aim is to understand the frequency of 435 in 31422939.

Let's proceed to step 1:
3 divided by 435 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 435

Step 2:
435 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 435

Advancing to step 3:
435 can be fit into 314 0 times, resulting in a remainder of 314.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 314 to get 314.
Bring next digit (2) of the dividend behind the 314 and repeat the process: 3142 / 435

Advancing to step 4:
If we divide 3142 by 435, we get 7 and a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 3045 from 3142 leaves us with 97.
Include the next digit (2) from the dividend after 97, then repeat: 972 / 435

Advancing to step 5:
435 can be fit into 972 2 times, resulting in a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 870 from 972 leaves us with 102.
Bring next digit (9) of the dividend behind the 102 and repeat the process: 1029 / 435

Step 6:
1029 divided by 435 is 2 with a remainder of 159.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
If we subtract 870 from 1029, we get 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 435

Step 7:
435 can be fit into 1593 3 times, resulting in a remainder of 288.
Put 3 as the next digit of the answer. 
Result so far: 7223.0
Deduct 1305 from 1593 and we're left with 288.
Append the next digit (9) from the dividend to 288 and continue with: 2889 / 435

Advancing to step 8:
435 can be fit into 2889 6 times, resulting in a remainder of 279.
Record the quotient 6 as the next digit in the result. 
Result so far: 72236.0
The remainder is 279 after subtracting 2610 from 2889.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 9:
When dividing 2790 by 435, we get 6 with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 72236.6
Subtract 2610 from 2790 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
435 can be fit into 1800 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 72236.64
If we take 1740 away from 1800, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 435, we get 1 with a remainder of 165.
Record the quotient 1 as the next digit in the result. 
Result so far: 72236.641
If we subtract 435 from 600, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 12:
435 goes into 1650 3 times with a remainder of 345.
Put 3 as the next digit of the answer. 
Result so far: 72236.6413
The remainder is 345 after subtracting 1305 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 13:
435 goes into 3450 7 times with a remainder of 405.
Put 7 as the next digit of the answer. 
Result so far: 72236.64137
If we subtract 3045 from 3450, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 14:
If we divide 4050 by 435, we get 9 and a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 72236.641379
Subtract 3915 from 4050 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 15:
The number 435 fits into 1350 3 times, leaving a remainder of 45.
The next digit of our result is 3. 
Result so far: 72236.6413793
If we take 1305 away from 1350, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
435 can be fit into 450 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 72236.64137931
Subtract 435 from 450 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 72236.64137931, with a leftover of 1.5e-08.
