We're dividing 36557126 by 278 
The aim is to understand the frequency of 278 in 36557126.

Let's proceed to step 1:
When dividing 3 by 278, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 278

On to step 2:
36 divided by 278 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 278

Step 3:
When dividing 365 by 278, we get 1 with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 278 from 365, we get 87.
Grab the next digit (5) from the dividend, add it to 87, then carry on: 875 / 278

Moving on to step 4:
278 can be fit into 875 3 times, resulting in a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 834 from 875 leaves us with 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 278

Moving on to step 5:
The number 278 fits into 417 1 times, leaving a remainder of 139.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 278 from 417 and we're left with 139.
Take the next digit (1) from the dividend and append it to 139, then repeat: 1391 / 278

Advancing to step 6:
If we divide 1391 by 278, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 1315.0
Subtract 1390 from 1391 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 278

Step 7:
278 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 13150.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 278

Moving on to step 8:
126 divided by 278 is 0 with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 131500.0
Deduct 0 from 126 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
The number 278 fits into 1260 4 times, leaving a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 131500.4
If we take 1112 away from 1260, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
278 can be fit into 1480 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 131500.45
Subtracting 1390 from 1480 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
278 goes into 900 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 131500.453
If we subtract 834 from 900, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
660 divided by 278 is 2 with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 131500.4532
Subtracting 556 from 660 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
278 goes into 1040 3 times with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 131500.45323
Deduct 834 from 1040 and we're left 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.

Moving on to step 14:
2060 divided by 278 is 7 with a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 131500.453237
Subtract 1946 from 2060 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 15:
The number 278 fits into 1140 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 131500.4532374
Subtract 1112 from 1140 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
If we divide 280 by 278, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 131500.45323741
Subtract 278 from 280 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 131500.45323741, with a leftover of 2e-09.
