66618440 ÷ 777 
The aim is to understand the frequency of 777 in 66618440.

Going ahead to step 1:
777 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 777

Advancing to step 2:
777 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 777

Advancing to step 3:
777 goes into 666 0 times with a remainder of 666.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 666, we get 666.
Take the next digit (1) from the dividend and append it to 666, then repeat: 6661 / 777

Advancing to step 4:
777 can be fit into 6661 8 times, resulting in a remainder of 445.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6216 away from 6661, we end up with 445.
Grab the next digit (8) from the dividend, add it to 445, then carry on: 4458 / 777

Step 5:
777 goes into 4458 5 times with a remainder of 573.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 3885 away from 4458, we end up with 573.
Take the next digit (4) from the dividend and append it to 573, then repeat: 5734 / 777

On to step 6:
5734 divided by 777 is 7 with a remainder of 295.
The next digit of our result is 7. 
Result so far: 857.0
Subtracting 5439 from 5734 leaves us with 295.
Bring next digit (4) of the dividend behind the 295 and repeat the process: 2954 / 777

Step 7:
When dividing 2954 by 777, we get 3 with a remainder of 623.
Record the quotient 3 as the next digit in the result. 
Result so far: 8573.0
If we take 2331 away from 2954, we end up with 623.
Grab the next digit (0) from the dividend, add it to 623, then carry on: 6230 / 777

Step 8:
If we divide 6230 by 777, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 85738.0
Deduct 6216 from 6230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
777 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 85738.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
The number 777 fits into 1400 1 times, leaving a remainder of 623.
Record the quotient 1 as the next digit in the result. 
Result so far: 85738.01
Subtracting 777 from 1400 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 11:
6230 divided by 777 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 85738.018
Deduct 6216 from 6230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
777 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 85738.018
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
777 goes into 1400 1 times with a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 85738.01801
If we subtract 777 from 1400, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 14:
The number 777 fits into 6230 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 85738.018018
Subtract 6216 from 6230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
777 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 85738.018018
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
The number 777 fits into 1400 1 times, leaving a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 85738.01801801
Subtract 777 from 1400 to get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

The quotient of the division is 85738.01801801, and the remainder is 6.23e-07.
