910446 ÷ 77 
The aim is to understand the frequency of 77 in 910446.

Moving on to step 1:
77 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 77

Moving on to step 2:
If we divide 91 by 77, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 77 from 91 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 77

On to step 3:
When dividing 140 by 77, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 77 from 140 leaves us with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 77

On to step 4:
If we divide 634 by 77, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 118.0
The remainder is 18 after subtracting 616 from 634.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 77

Let's proceed to step 5:
If we divide 184 by 77, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 1182.0
Subtract 154 from 184 to get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 77

Moving on to step 6:
77 goes into 306 3 times with a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 11823.0
Subtract 231 from 306 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 11823.9
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 8:
If we divide 570 by 77, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 11823.97
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
310 divided by 77 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11823.974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11823.974
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 77, we get 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 11823.97402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
The number 77 fits into 460 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 11823.974025
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
77 can be fit into 750 9 times, resulting in a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 11823.9740259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
77 goes into 570 7 times with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 11823.97402597
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 11823.97402597 with a remaining 3.1e-08.
