67123409 ÷ 446 
The aim is to understand the frequency of 446 in 67123409.

Going ahead to step 1:
When dividing 6 by 446, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 446

Advancing to step 2:
The number 446 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 446

Let's proceed to step 3:
446 can be fit into 671 1 times, resulting in a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 225 after subtracting 446 from 671.
Bring next digit (2) of the dividend behind the 225 and repeat the process: 2252 / 446

Advancing to step 4:
When dividing 2252 by 446, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2230 from 2252 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 446

Let's proceed to step 5:
446 goes into 223 0 times with a remainder of 223.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 223 and we're left with 223.
Fetch the next digit (4) from the dividend, attach it to 223 and continue: 2234 / 446

On to step 6:
446 can be fit into 2234 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1505.0
Subtracting 2230 from 2234 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 446

Moving on to step 7:
When dividing 40 by 446, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 15050.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 446

On to step 8:
446 can be fit into 409 0 times, resulting in a remainder of 409.
Write down 0 as next digit of the result. 
Result so far: 150500.0
If we take 0 away from 409, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 9:
4090 divided by 446 is 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 150500.9
Deduct 4014 from 4090 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
The number 446 fits into 760 1 times, leaving a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 150500.91
Subtracting 446 from 760 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 11:
The number 446 fits into 3140 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 150500.917
If we take 3122 away from 3140, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
446 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 150500.917
If we subtract 0 from 180, we 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.

Let's proceed to step 13:
When dividing 1800 by 446, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 150500.91704
Deduct 1784 from 1800 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
446 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 150500.91704
Deduct 0 from 160 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.

Moving on to step 15:
446 can be fit into 1600 3 times, resulting in a remainder of 262.
Use 3 as the next digit of our solution. 
Result so far: 150500.9170403
Subtracting 1338 from 1600 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 16:
446 can be fit into 2620 5 times, resulting in a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 150500.91704035
Subtract 2230 from 2620 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 150500.91704035 with a remainder of 3.9e-07.
