16159996 ÷ 455 
The aim is to understand the frequency of 455 in 16159996.

Advancing to step 1:
1 divided by 455 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 455

Going ahead to step 2:
The number 455 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 455

Going ahead to step 3:
The number 455 fits into 161 0 times, leaving a remainder of 161.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 161 and we're left with 161.
Fetch the next digit (5) from the dividend, attach it to 161 and continue: 1615 / 455

Let's proceed to step 4:
455 can be fit into 1615 3 times, resulting in a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1365 from 1615 and we're left with 250.
Grab the next digit (9) from the dividend, add it to 250, then carry on: 2509 / 455

Moving on to step 5:
If we divide 2509 by 455, we get 5 and a remainder of 234.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 234 after subtracting 2275 from 2509.
Grab the next digit (9) from the dividend, add it to 234, then carry on: 2349 / 455

Moving on to step 6:
If we divide 2349 by 455, we get 5 and a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
If we take 2275 away from 2349, we end up with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 455

Moving on to step 7:
The number 455 fits into 749 1 times, leaving a remainder of 294.
The next digit of our result is 1. 
Result so far: 3551.0
Subtracting 455 from 749 leaves us with 294.
Bring next digit (6) of the dividend behind the 294 and repeat the process: 2946 / 455

Going ahead to step 8:
The number 455 fits into 2946 6 times, leaving a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 35516.0
Deduct 2730 from 2946 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 9:
The number 455 fits into 2160 4 times, leaving a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 35516.4
If we subtract 1820 from 2160, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
If we divide 3400 by 455, we get 7 and a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 35516.47
Subtract 3185 from 3400 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 11:
When dividing 2150 by 455, we get 4 with a remainder of 330.
Use 4 as the next digit of our solution. 
Result so far: 35516.474
Subtracting 1820 from 2150 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 12:
455 can be fit into 3300 7 times, resulting in a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 35516.4747
If we subtract 3185 from 3300, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
The number 455 fits into 1150 2 times, leaving a remainder of 240.
The next digit of our result is 2. 
Result so far: 35516.47472
If we take 910 away from 1150, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
455 can be fit into 2400 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 35516.474725
If we take 2275 away from 2400, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
The number 455 fits into 1250 2 times, leaving a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 35516.4747252
Subtract 910 from 1250 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
455 can be fit into 3400 7 times, resulting in a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 35516.47472527
Subtract 3185 from 3400 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 35516.47472527, with a leftover of 2.15e-07.
