We're dividing 13661257 by 475 
The aim is to understand the frequency of 475 in 13661257.

On to step 1:
475 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 475

Step 2:
475 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 475

Let's proceed to step 3:
475 goes into 136 0 times with a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 136 and we're left with 136.
Bring next digit (6) of the dividend behind the 136 and repeat the process: 1366 / 475

On to step 4:
If we divide 1366 by 475, we get 2 and a remainder of 416.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 950 from 1366 and we're left with 416.
Append the next digit (1) from the dividend to 416 and continue with: 4161 / 475

Advancing to step 5:
If we divide 4161 by 475, we get 8 and a remainder of 361.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 361 after subtracting 3800 from 4161.
Append the next digit (2) from the dividend to 361 and continue with: 3612 / 475

Let's proceed to step 6:
If we divide 3612 by 475, we get 7 and a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 287.0
The remainder is 287 after subtracting 3325 from 3612.
Grab the next digit (5) from the dividend, add it to 287, then carry on: 2875 / 475

Advancing to step 7:
The number 475 fits into 2875 6 times, leaving a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 2876.0
If we subtract 2850 from 2875, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 475

Advancing to step 8:
475 can be fit into 257 0 times, resulting in a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 28760.0
If we take 0 away from 257, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
If we divide 2570 by 475, we get 5 and a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 28760.5
Deduct 2375 from 2570 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
When dividing 1950 by 475, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 28760.54
Deduct 1900 from 1950 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
The number 475 fits into 500 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 28760.541
Subtracting 475 from 500 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
475 can be fit into 250 0 times, resulting in a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 28760.541
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 13:
If we divide 2500 by 475, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 28760.54105
The remainder is 125 after subtracting 2375 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
When dividing 1250 by 475, we get 2 with a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 28760.541052
If we subtract 950 from 1250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
475 can be fit into 3000 6 times, resulting in a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 28760.5410526
If we subtract 2850 from 3000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
475 can be fit into 1500 3 times, resulting in a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 28760.54105263
If we subtract 1425 from 1500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 28760.54105263, and the remainder is 7.5e-08.
