83490861 divided by 278 
The aim is to understand the frequency of 278 in 83490861.

Let's proceed to step 1:
If we divide 8 by 278, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 278

Advancing to step 2:
83 divided by 278 is 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 278

Going ahead to step 3:
When dividing 834 by 278, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 834 from 834.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 278

On to step 4:
When dividing 9 by 278, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 278

On to step 5:
The number 278 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
If we take 0 away from 90, we end up with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 278

Going ahead to step 6:
The number 278 fits into 908 3 times, leaving a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 3003.0
Subtracting 834 from 908 leaves us with 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 278

Step 7:
746 divided by 278 is 2 with a remainder of 190.
The next digit of our result is 2. 
Result so far: 30032.0
Subtracting 556 from 746 leaves us with 190.
Append the next digit (1) from the dividend to 190 and continue with: 1901 / 278

Advancing to step 8:
If we divide 1901 by 278, we get 6 and a remainder of 233.
Write down 6 as next digit of the result. 
Result so far: 300326.0
The remainder is 233 after subtracting 1668 from 1901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 9:
When dividing 2330 by 278, we get 8 with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 300326.8
Subtracting 2224 from 2330 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
278 can be fit into 1060 3 times, resulting in a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 300326.83
If we take 834 away from 1060, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 11:
278 goes into 2260 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 300326.838
If we take 2224 away from 2260, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
278 can be fit into 360 1 times, resulting in a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 300326.8381
Subtract 278 from 360 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
If we divide 820 by 278, we get 2 and a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 300326.83812
Subtract 556 from 820 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 14:
If we divide 2640 by 278, we get 9 and a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 300326.838129
Subtract 2502 from 2640 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 15:
When dividing 1380 by 278, we get 4 with a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 300326.8381294
The remainder is 268 after subtracting 1112 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 16:
When dividing 2680 by 278, we get 9 with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 300326.83812949
Subtracting 2502 from 2680 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 300326.83812949 and a remainder of 1.78e-07.
