We look at the division of 32121175 by 770 
The aim is to understand the frequency of 770 in 32121175.

On to step 1:
If we divide 3 by 770, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 770

Advancing to step 2:
32 divided by 770 is 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 770

Advancing to step 3:
770 can be fit into 321 0 times, resulting in a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 321 after subtracting 0 from 321.
Append the next digit (2) from the dividend to 321 and continue with: 3212 / 770

On to step 4:
When dividing 3212 by 770, we get 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3080 away from 3212, we end up with 132.
Take the next digit (1) from the dividend and append it to 132, then repeat: 1321 / 770

Advancing to step 5:
770 goes into 1321 1 times with a remainder of 551.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 770 from 1321 to get 551.
Append the next digit (1) from the dividend to 551 and continue with: 5511 / 770

Let's proceed to step 6:
The number 770 fits into 5511 7 times, leaving a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 417.0
If we take 5390 away from 5511, we end up with 121.
Take the next digit (7) from the dividend and append it to 121, then repeat: 1217 / 770

Step 7:
770 can be fit into 1217 1 times, resulting in a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 4171.0
Subtract 770 from 1217 to get 447.
Take the next digit (5) from the dividend and append it to 447, then repeat: 4475 / 770

On to step 8:
770 goes into 4475 5 times with a remainder of 625.
The number 5 becomes the next digit in our result. 
Result so far: 41715.0
If we subtract 3850 from 4475, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 9:
When dividing 6250 by 770, we get 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 41715.8
Subtract 6160 from 6250 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
If we divide 900 by 770, we get 1 and a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 41715.81
Subtract 770 from 900 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
770 goes into 1300 1 times with a remainder of 530.
Record the quotient 1 as the next digit in the result. 
Result so far: 41715.811
The remainder is 530 after subtracting 770 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Our division results in 41715.811 with a remaining 0.053.
