83905194 ÷ 770 
The aim is to understand the frequency of 770 in 83905194.

Going ahead to step 1:
When dividing 8 by 770, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 770

Going ahead to step 2:
The number 770 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 770

Moving on to step 3:
839 divided by 770 is 1 with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 770 from 839 and we're left with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 770

On to step 4:
770 goes into 690 0 times with a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 690 leaves us with 690.
Fetch the next digit (5) from the dividend, attach it to 690 and continue: 6905 / 770

Step 5:
If we divide 6905 by 770, we get 8 and a remainder of 745.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 6160 from 6905 to get 745.
Take the next digit (1) from the dividend and append it to 745, then repeat: 7451 / 770

Moving on to step 6:
The number 770 fits into 7451 9 times, leaving a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
The remainder is 521 after subtracting 6930 from 7451.
Include the next digit (9) from the dividend after 521, then repeat: 5219 / 770

Going ahead to step 7:
When dividing 5219 by 770, we get 6 with a remainder of 599.
Use 6 as the next digit of our solution. 
Result so far: 10896.0
If we subtract 4620 from 5219, we get 599.
Grab the next digit (4) from the dividend, add it to 599, then carry on: 5994 / 770

Moving on to step 8:
770 goes into 5994 7 times with a remainder of 604.
The number 7 becomes the next digit in our result. 
Result so far: 108967.0
Deduct 5390 from 5994 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 9:
770 goes into 6040 7 times with a remainder of 650.
Record the quotient 7 as the next digit in the result. 
Result so far: 108967.7
The remainder is 650 after subtracting 5390 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 10:
If we divide 6500 by 770, we get 8 and a remainder of 340.
The number 8 becomes the next digit in our result. 
Result so far: 108967.78
If we take 6160 away from 6500, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
When dividing 3400 by 770, we get 4 with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 108967.784
The remainder is 320 after subtracting 3080 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
If we divide 3200 by 770, we get 4 and a remainder of 120.
The next digit of our result is 4. 
Result so far: 108967.7844
The remainder is 120 after subtracting 3080 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 108967.7844 and a remainder of 0.0012.
