Let's divide 51259565 by 277
The aim is to understand the frequency of 277 in 51259565.

Step 1:
277 can be fit into 5 0 times, resulting in 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 277

Going ahead to step 2:
When dividing 51 by 277, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 277

On to step 3:
When dividing 512 by 277, we get 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 277 from 512, we get 235.
Take the next digit (5) from the dividend and append it to 235, then repeat: 2355 / 277

Advancing to step 4:
If we divide 2355 by 277, we get 8 and a remainder of 139.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 2216 from 2355 and we're left with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 277

Advancing to step 5:
If we divide 1399 by 277, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 1385 away from 1399, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 277

Advancing to step 6:
277 can be fit into 145 0 times, resulting in a remainder of 145.
The next digit of our result is 0. 
Result so far: 1850.0
If we subtract 0 from 145, we get 145.
Take the next digit (6) from the dividend and append it to 145, then repeat: 1456 / 277

On to step 7:
1456 divided by 277 is 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 18505.0
Deduct 1385 from 1456 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 277

Let's proceed to step 8:
277 can be fit into 715 2 times, resulting in a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 185052.0
If we take 554 away from 715, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 9:
If we divide 1610 by 277, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 185052.5
If we subtract 1385 from 1610, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 10:
When dividing 2250 by 277, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 185052.58
Subtract 2216 from 2250 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
If we divide 340 by 277, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 185052.581
Deduct 277 from 340 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
630 divided by 277 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 185052.5812
Subtract 554 from 630 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
277 goes into 760 2 times with a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 185052.58122
Subtracting 554 from 760 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final outcome is 185052.58122, with a leftover of 0.000206.
