841999 divided by 77 
The aim is to understand the frequency of 77 in 841999.

Let's proceed to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 77

Let's proceed to step 2:
77 can be fit into 84 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 84, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 77

Advancing to step 3:
If we divide 71 by 77, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 77

On to step 4:
If we divide 719 by 77, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 693 from 719, we get 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 77

Step 5:
77 goes into 269 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 1093.0
If we take 231 away from 269, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 77

Let's proceed to step 6:
389 divided by 77 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 10935.0
If we take 385 away from 389, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
77 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10935.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10935.05
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 77 is 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10935.051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 10:
730 divided by 77 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 10935.0519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 77, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 10935.05194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10935.051948
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
77 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10935.051948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 10935.05194805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 10935.05194805 and a remainder of 1.5e-08.
