74578081 ÷ 770 
The aim is to understand the frequency of 770 in 74578081.

Going ahead to step 1:
770 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 770

On to step 2:
If we divide 74 by 770, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 770

Advancing to step 3:
770 can be fit into 745 0 times, resulting in a remainder of 745.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 745, we get 745.
Include the next digit (7) from the dividend after 745, then repeat: 7457 / 770

Let's proceed to step 4:
770 can be fit into 7457 9 times, resulting in a remainder of 527.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6930 from 7457 to get 527.
Grab the next digit (8) from the dividend, add it to 527, then carry on: 5278 / 770

Going ahead to step 5:
If we divide 5278 by 770, we get 6 and a remainder of 658.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 658 after subtracting 4620 from 5278.
Bring next digit (0) of the dividend behind the 658 and repeat the process: 6580 / 770

Advancing to step 6:
6580 divided by 770 is 8 with a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 968.0
If we subtract 6160 from 6580, we get 420.
Bring next digit (8) of the dividend behind the 420 and repeat the process: 4208 / 770

Step 7:
When dividing 4208 by 770, we get 5 with a remainder of 358.
Use 5 as the next digit of our solution. 
Result so far: 9685.0
Subtract 3850 from 4208 to get 358.
Bring next digit (1) of the dividend behind the 358 and repeat the process: 3581 / 770

Moving on to step 8:
770 goes into 3581 4 times with a remainder of 501.
Put 4 as the next digit of the answer. 
Result so far: 96854.0
Subtract 3080 from 3581 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 9:
When dividing 5010 by 770, we get 6 with a remainder of 390.
The next digit of our result is 6. 
Result so far: 96854.6
Deduct 4620 from 5010 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
770 can be fit into 3900 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 96854.65
The remainder is 50 after subtracting 3850 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 770, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 96854.65
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 12:
The number 770 fits into 5000 6 times, leaving a remainder of 380.
Use 6 as the next digit of our solution. 
Result so far: 96854.6506
Subtract 4620 from 5000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
770 goes into 3800 4 times with a remainder of 720.
The next digit of our result is 4. 
Result so far: 96854.65064
Subtract 3080 from 3800 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 14:
If we divide 7200 by 770, we get 9 and a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 96854.650649
If we take 6930 away from 7200, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 15:
When dividing 2700 by 770, we get 3 with a remainder of 390.
The number 3 becomes the next digit in our result. 
Result so far: 96854.6506493
Subtracting 2310 from 2700 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 16:
770 can be fit into 3900 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 96854.65064935
Subtract 3850 from 3900 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 96854.65064935, and the remainder is 5e-08.
