6800401 divided by 770 
The aim is to understand the frequency of 770 in 6800401.

Advancing to step 1:
When dividing 6 by 770, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 770

Step 2:
The number 770 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 770

Let's proceed to step 3:
If we divide 680 by 770, we get 0 and a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 680 after subtracting 0 from 680.
Append the next digit (0) from the dividend to 680 and continue with: 6800 / 770

Advancing to step 4:
When dividing 6800 by 770, we get 8 with a remainder of 640.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 640 after subtracting 6160 from 6800.
Grab the next digit (4) from the dividend, add it to 640, then carry on: 6404 / 770

Advancing to step 5:
The number 770 fits into 6404 8 times, leaving a remainder of 244.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 6160 from 6404 to get 244.
Grab the next digit (0) from the dividend, add it to 244, then carry on: 2440 / 770

Advancing to step 6:
2440 divided by 770 is 3 with a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 883.0
If we take 2310 away from 2440, we end up with 130.
Include the next digit (1) from the dividend after 130, then repeat: 1301 / 770

Advancing to step 7:
1301 divided by 770 is 1 with a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 8831.0
Deduct 770 from 1301 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 8:
5310 divided by 770 is 6 with a remainder of 690.
Write down 6 as next digit of the result. 
Result so far: 8831.6
If we take 4620 away from 5310, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 9:
770 goes into 6900 8 times with a remainder of 740.
The next digit of our result is 8. 
Result so far: 8831.68
If we subtract 6160 from 6900, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 10:
The number 770 fits into 7400 9 times, leaving a remainder of 470.
Write down 9 as next digit of the result. 
Result so far: 8831.689
If we subtract 6930 from 7400, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
The number 770 fits into 4700 6 times, leaving a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 8831.6896
The remainder is 80 after subtracting 4620 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
770 goes into 800 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 8831.68961
If we take 770 away from 800, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
The number 770 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 8831.68961
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
When dividing 3000 by 770, we get 3 with a remainder of 690.
The next digit of our result is 3. 
Result so far: 8831.6896103
Subtract 2310 from 3000 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 15:
770 can be fit into 6900 8 times, resulting in a remainder of 740.
Put 8 as the next digit of the answer. 
Result so far: 8831.68961038
If we subtract 6160 from 6900, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final outcome is 8831.68961038, with a leftover of 7.4e-07.
