Let's divide 70421334 by 770
The aim is to understand the frequency of 770 in 70421334.

Advancing to step 1:
The number 770 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 770

Going ahead to step 2:
When dividing 70 by 770, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 770

Step 3:
704 divided by 770 is 0 with a remainder of 704.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 704, we end up with 704.
Fetch the next digit (2) from the dividend, attach it to 704 and continue: 7042 / 770

Moving on to step 4:
If we divide 7042 by 770, we get 9 and a remainder of 112.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6930 from 7042, we get 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 770

Step 5:
When dividing 1121 by 770, we get 1 with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 770 from 1121 leaves us with 351.
Append the next digit (3) from the dividend to 351 and continue with: 3513 / 770

Advancing to step 6:
When dividing 3513 by 770, we get 4 with a remainder of 433.
Write down 4 as next digit of the result. 
Result so far: 914.0
If we subtract 3080 from 3513, we get 433.
Take the next digit (3) from the dividend and append it to 433, then repeat: 4333 / 770

Advancing to step 7:
770 can be fit into 4333 5 times, resulting in a remainder of 483.
Use 5 as the next digit of our solution. 
Result so far: 9145.0
Deduct 3850 from 4333 and we're left with 483.
Bring next digit (4) of the dividend behind the 483 and repeat the process: 4834 / 770

Let's proceed to step 8:
770 can be fit into 4834 6 times, resulting in a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 91456.0
If we take 4620 away from 4834, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 9:
When dividing 2140 by 770, we get 2 with a remainder of 600.
Put 2 as the next digit of the answer. 
Result so far: 91456.2
Deduct 1540 from 2140 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
When dividing 6000 by 770, we get 7 with a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 91456.27
If we take 5390 away from 6000, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 11:
6100 divided by 770 is 7 with a remainder of 710.
The number 7 becomes the next digit in our result. 
Result so far: 91456.277
If we take 5390 away from 6100, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final outcome is 91456.277, with a leftover of 0.071.
