We look at the division of 13503945 by 462 
The aim is to understand the frequency of 462 in 13503945.

On to step 1:
If we divide 1 by 462, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 462

Moving on to step 2:
462 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 462

On to step 3:
When dividing 135 by 462, we get 0 with a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 135, we end up with 135.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 462

Let's proceed to step 4:
The number 462 fits into 1350 2 times, leaving a remainder of 426.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 924 from 1350 to get 426.
Include the next digit (3) from the dividend after 426, then repeat: 4263 / 462

Going ahead to step 5:
When dividing 4263 by 462, we get 9 with a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 4158 away from 4263, we end up with 105.
Take the next digit (9) from the dividend and append it to 105, then repeat: 1059 / 462

Let's proceed to step 6:
462 can be fit into 1059 2 times, resulting in a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 292.0
Subtract 924 from 1059 to get 135.
Take the next digit (4) from the dividend and append it to 135, then repeat: 1354 / 462

On to step 7:
462 goes into 1354 2 times with a remainder of 430.
Put 2 as the next digit of the answer. 
Result so far: 2922.0
Deduct 924 from 1354 and we're left with 430.
Grab the next digit (5) from the dividend, add it to 430, then carry on: 4305 / 462

Advancing to step 8:
If we divide 4305 by 462, we get 9 and a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 29229.0
Subtracting 4158 from 4305 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
462 goes into 1470 3 times with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 29229.3
If we take 1386 away from 1470, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
When dividing 840 by 462, we get 1 with a remainder of 378.
Write down 1 as next digit of the result. 
Result so far: 29229.31
If we subtract 462 from 840, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 11:
462 can be fit into 3780 8 times, resulting in a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 29229.318
If we take 3696 away from 3780, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
If we divide 840 by 462, we get 1 and a remainder of 378.
The next digit of our result is 1. 
Result so far: 29229.3181
Subtracting 462 from 840 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 13:
When dividing 3780 by 462, we get 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 29229.31818
Subtracting 3696 from 3780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
462 can be fit into 840 1 times, resulting in a remainder of 378.
Record the quotient 1 as the next digit in the result. 
Result so far: 29229.318181
Subtracting 462 from 840 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 15:
3780 divided by 462 is 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 29229.3181818
Deduct 3696 from 3780 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 16:
840 divided by 462 is 1 with a remainder of 378.
The next digit of our result is 1. 
Result so far: 29229.31818181
Subtract 462 from 840 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 29229.31818181, with a leftover of 3.78e-07.
