54094561 ÷ 402 
The aim is to understand the frequency of 402 in 54094561.

Moving on to step 1:
402 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 402

Going ahead to step 2:
402 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 402

Step 3:
402 can be fit into 540 1 times, resulting in a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 402 from 540, we get 138.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 402

Let's proceed to step 4:
If we divide 1389 by 402, we get 3 and a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1206 from 1389 leaves us with 183.
Fetch the next digit (4) from the dividend, attach it to 183 and continue: 1834 / 402

Let's proceed to step 5:
When dividing 1834 by 402, we get 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 134.0
If we take 1608 away from 1834, we end up with 226.
Grab the next digit (5) from the dividend, add it to 226, then carry on: 2265 / 402

Let's proceed to step 6:
If we divide 2265 by 402, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 1345.0
If we subtract 2010 from 2265, we get 255.
Append the next digit (6) from the dividend to 255 and continue with: 2556 / 402

Let's proceed to step 7:
402 can be fit into 2556 6 times, resulting in a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 13456.0
If we subtract 2412 from 2556, we get 144.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 402

Let's proceed to step 8:
1441 divided by 402 is 3 with a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 134563.0
If we take 1206 away from 1441, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 9:
The number 402 fits into 2350 5 times, leaving a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 134563.5
Subtracting 2010 from 2350 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
402 goes into 3400 8 times with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 134563.58
The remainder is 184 after subtracting 3216 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 11:
If we divide 1840 by 402, we get 4 and a remainder of 232.
The next digit of our result is 4. 
Result so far: 134563.584
Subtract 1608 from 1840 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
When dividing 2320 by 402, we get 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 134563.5845
Subtracting 2010 from 2320 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 13:
402 goes into 3100 7 times with a remainder of 286.
The next digit of our result is 7. 
Result so far: 134563.58457
If we take 2814 away from 3100, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 14:
When dividing 2860 by 402, we get 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 134563.584577
If we subtract 2814 from 2860, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 134563.584577, with a leftover of 4.6e-06.
