12630372 ÷ 770 
The aim is to understand the frequency of 770 in 12630372.

On to step 1:
If we divide 1 by 770, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 770

Step 2:
12 divided by 770 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 770

Advancing to step 3:
770 goes into 126 0 times with a remainder of 126.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Grab the next digit (3) from the dividend, add it to 126, then carry on: 1263 / 770

Going ahead to step 4:
770 can be fit into 1263 1 times, resulting in a remainder of 493.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 770 from 1263 and we're left with 493.
Bring next digit (0) of the dividend behind the 493 and repeat the process: 4930 / 770

Advancing to step 5:
770 can be fit into 4930 6 times, resulting in a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 4620 from 4930, we get 310.
Take the next digit (3) from the dividend and append it to 310, then repeat: 3103 / 770

Advancing to step 6:
If we divide 3103 by 770, we get 4 and a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 3080 away from 3103, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 770

Let's proceed to step 7:
770 can be fit into 237 0 times, resulting in a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 1640.0
Subtracting 0 from 237 leaves us with 237.
Take the next digit (2) from the dividend and append it to 237, then repeat: 2372 / 770

Going ahead to step 8:
2372 divided by 770 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 16403.0
The remainder is 62 after subtracting 2310 from 2372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
If we divide 620 by 770, we get 0 and a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 16403.0
The remainder is 620 after subtracting 0 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
When dividing 6200 by 770, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 16403.08
If we subtract 6160 from 6200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 770, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 16403.08
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
4000 divided by 770 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 16403.0805
Deduct 3850 from 4000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
If we divide 1500 by 770, we get 1 and a remainder of 730.
The number 1 becomes the next digit in our result. 
Result so far: 16403.08051
Subtract 770 from 1500 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 14:
770 can be fit into 7300 9 times, resulting in a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 16403.080519
Subtract 6930 from 7300 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 15:
When dividing 3700 by 770, we get 4 with a remainder of 620.
Record the quotient 4 as the next digit in the result. 
Result so far: 16403.0805194
Subtract 3080 from 3700 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 16:
6200 divided by 770 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 16403.08051948
Subtract 6160 from 6200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 16403.08051948 with a remaining 4e-08.
