Let's divide 77794585 by 490
The aim is to understand the frequency of 490 in 77794585.

On to step 1:
The number 490 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 490

Advancing to step 2:
When dividing 77 by 490, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 490

Moving on to step 3:
490 can be fit into 777 1 times, resulting in a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 490 from 777 to get 287.
Include the next digit (9) from the dividend after 287, then repeat: 2879 / 490

Advancing to step 4:
When dividing 2879 by 490, we get 5 with a remainder of 429.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2450 from 2879, we get 429.
Include the next digit (4) from the dividend after 429, then repeat: 4294 / 490

Let's proceed to step 5:
The number 490 fits into 4294 8 times, leaving a remainder of 374.
Write down 8 as next digit of the result. 
Result so far: 158.0
Deduct 3920 from 4294 and we're left with 374.
Fetch the next digit (5) from the dividend, attach it to 374 and continue: 3745 / 490

Advancing to step 6:
490 can be fit into 3745 7 times, resulting in a remainder of 315.
Record the quotient 7 as the next digit in the result. 
Result so far: 1587.0
Deduct 3430 from 3745 and we're left with 315.
Grab the next digit (8) from the dividend, add it to 315, then carry on: 3158 / 490

Advancing to step 7:
If we divide 3158 by 490, we get 6 and a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 15876.0
The remainder is 218 after subtracting 2940 from 3158.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 490

Let's proceed to step 8:
2185 divided by 490 is 4 with a remainder of 225.
Put 4 as the next digit of the answer. 
Result so far: 158764.0
Deduct 1960 from 2185 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
490 can be fit into 2250 4 times, resulting in a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 158764.4
Subtract 1960 from 2250 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
490 goes into 2900 5 times with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 158764.45
The remainder is 450 after subtracting 2450 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 11:
If we divide 4500 by 490, we get 9 and a remainder of 90.
The next digit of our result is 9. 
Result so far: 158764.459
The remainder is 90 after subtracting 4410 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
490 goes into 900 1 times with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 158764.4591
Deduct 490 from 900 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 13:
490 goes into 4100 8 times with a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 158764.45918
Subtract 3920 from 4100 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
If we divide 1800 by 490, we get 3 and a remainder of 330.
Use 3 as the next digit of our solution. 
Result so far: 158764.459183
Subtract 1470 from 1800 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 15:
When dividing 3300 by 490, we get 6 with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 158764.4591836
Deduct 2940 from 3300 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 16:
490 can be fit into 3600 7 times, resulting in a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 158764.45918367
Deduct 3430 from 3600 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

After the division, we end up with 158764.45918367 and a remainder of 1.7e-07.
