53546139 divided by 427 
The aim is to understand the frequency of 427 in 53546139.

Step 1:
When dividing 5 by 427, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 427

Going ahead to step 2:
427 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 427

Step 3:
427 can be fit into 535 1 times, resulting in a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 427 away from 535, we end up with 108.
Grab the next digit (4) from the dividend, add it to 108, then carry on: 1084 / 427

Going ahead to step 4:
427 can be fit into 1084 2 times, resulting in a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 854 away from 1084, we end up with 230.
Grab the next digit (6) from the dividend, add it to 230, then carry on: 2306 / 427

Moving on to step 5:
If we divide 2306 by 427, we get 5 and a remainder of 171.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 2135 away from 2306, we end up with 171.
Fetch the next digit (1) from the dividend, attach it to 171 and continue: 1711 / 427

Step 6:
If we divide 1711 by 427, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
Subtract 1708 from 1711 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 427

Going ahead to step 7:
33 divided by 427 is 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 12540.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 427

Moving on to step 8:
The number 427 fits into 339 0 times, leaving a remainder of 339.
Use 0 as the next digit of our solution. 
Result so far: 125400.0
If we take 0 away from 339, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 9:
If we divide 3390 by 427, we get 7 and a remainder of 401.
The number 7 becomes the next digit in our result. 
Result so far: 125400.7
If we subtract 2989 from 3390, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 10:
4010 divided by 427 is 9 with a remainder of 167.
The number 9 becomes the next digit in our result. 
Result so far: 125400.79
Subtracting 3843 from 4010 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 11:
The number 427 fits into 1670 3 times, leaving a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 125400.793
Deduct 1281 from 1670 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 12:
The number 427 fits into 3890 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 125400.7939
Deduct 3843 from 3890 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
427 can be fit into 470 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 125400.79391
If we take 427 away from 470, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
427 can be fit into 430 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 125400.793911
If we subtract 427 from 430, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 125400.793911 and a remainder of 3e-07.
