Let's divide 68145798 by 77
The aim is to understand the frequency of 77 in 68145798.

Moving on to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 77

Advancing to step 2:
When dividing 68 by 77, we get 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 77

Moving on to step 3:
When dividing 681 by 77, we get 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 616 away from 681, we end up with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 77

On to step 4:
654 divided by 77 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 38 after subtracting 616 from 654.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 77

On to step 5:
77 goes into 385 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 885.0
If we subtract 385 from 385, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 77

On to step 6:
When dividing 7 by 77, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 8850.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 77

Step 7:
77 goes into 79 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 88501.0
If we take 77 away from 79, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 77

On to step 8:
77 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 885010.0
Deduct 0 from 28 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 885010.3
If we take 231 away from 280, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
If we divide 490 by 77, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 885010.36
Subtract 462 from 490 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 11:
If we divide 280 by 77, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 885010.363
Deduct 231 from 280 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
If we divide 490 by 77, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 885010.3636
Deduct 462 from 490 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 77 fits into 280 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 885010.36363
If we take 231 away from 280, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
77 goes into 490 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 885010.363636
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
If we divide 280 by 77, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 885010.3636363
The remainder is 49 after subtracting 231 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
If we divide 490 by 77, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 885010.36363636
Subtracting 462 from 490 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 885010.36363636 and a remainder of 2.8e-08.
