77049733 ÷ 619 
The aim is to understand the frequency of 619 in 77049733.

Step 1:
619 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 619

On to step 2:
When dividing 77 by 619, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 619

On to step 3:
619 can be fit into 770 1 times, resulting in a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 619 from 770 and we're left with 151.
Include the next digit (4) from the dividend after 151, then repeat: 1514 / 619

On to step 4:
619 can be fit into 1514 2 times, resulting in a remainder of 276.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1238 from 1514 to get 276.
Append the next digit (9) from the dividend to 276 and continue with: 2769 / 619

On to step 5:
619 goes into 2769 4 times with a remainder of 293.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we subtract 2476 from 2769, we get 293.
Append the next digit (7) from the dividend to 293 and continue with: 2937 / 619

Advancing to step 6:
619 can be fit into 2937 4 times, resulting in a remainder of 461.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
Deduct 2476 from 2937 and we're left with 461.
Include the next digit (3) from the dividend after 461, then repeat: 4613 / 619

Going ahead to step 7:
619 can be fit into 4613 7 times, resulting in a remainder of 280.
The number 7 becomes the next digit in our result. 
Result so far: 12447.0
If we take 4333 away from 4613, we end up with 280.
Append the next digit (3) from the dividend to 280 and continue with: 2803 / 619

Moving on to step 8:
619 goes into 2803 4 times with a remainder of 327.
Put 4 as the next digit of the answer. 
Result so far: 124474.0
The remainder is 327 after subtracting 2476 from 2803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
3270 divided by 619 is 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 124474.5
Deduct 3095 from 3270 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 10:
1750 divided by 619 is 2 with a remainder of 512.
The next digit of our result is 2. 
Result so far: 124474.52
Subtract 1238 from 1750 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 11:
The number 619 fits into 5120 8 times, leaving a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 124474.528
Subtract 4952 from 5120 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
If we divide 1680 by 619, we get 2 and a remainder of 442.
Use 2 as the next digit of our solution. 
Result so far: 124474.5282
Deduct 1238 from 1680 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 13:
619 goes into 4420 7 times with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 124474.52827
If we subtract 4333 from 4420, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 14:
If we divide 870 by 619, we get 1 and a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 124474.528271
Deduct 619 from 870 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 15:
619 can be fit into 2510 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 124474.5282714
If we take 2476 away from 2510, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 16:
The number 619 fits into 340 0 times, leaving a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 124474.5282714
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 124474.5282714 with a remainder of 3.4e-07.
