We look at the division of 76380300 by 961 
The aim is to understand the frequency of 961 in 76380300.

Going ahead to step 1:
When dividing 7 by 961, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 961

Step 2:
The number 961 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 961

Moving on to step 3:
763 divided by 961 is 0 with a remainder of 763.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 763 after subtracting 0 from 763.
Grab the next digit (8) from the dividend, add it to 763, then carry on: 7638 / 961

Let's proceed to step 4:
961 goes into 7638 7 times with a remainder of 911.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 6727 from 7638 to get 911.
Grab the next digit (0) from the dividend, add it to 911, then carry on: 9110 / 961

Advancing to step 5:
961 goes into 9110 9 times with a remainder of 461.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 8649 from 9110 leaves us with 461.
Bring next digit (3) of the dividend behind the 461 and repeat the process: 4613 / 961

Moving on to step 6:
If we divide 4613 by 961, we get 4 and a remainder of 769.
Use 4 as the next digit of our solution. 
Result so far: 794.0
Subtracting 3844 from 4613 leaves us with 769.
Include the next digit (0) from the dividend after 769, then repeat: 7690 / 961

Going ahead to step 7:
The number 961 fits into 7690 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7948.0
Subtracting 7688 from 7690 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 961

Step 8:
The number 961 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 79480.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 961 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 79480.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
When dividing 2000 by 961, we get 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 79480.02
If we subtract 1922 from 2000, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
If we divide 780 by 961, we get 0 and a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 79480.02
If we subtract 0 from 780, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 12:
The number 961 fits into 7800 8 times, leaving a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 79480.0208
Deduct 7688 from 7800 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
961 goes into 1120 1 times with a remainder of 159.
The next digit of our result is 1. 
Result so far: 79480.02081
If we subtract 961 from 1120, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 14:
961 goes into 1590 1 times with a remainder of 629.
Use 1 as the next digit of our solution. 
Result so far: 79480.020811
Subtracting 961 from 1590 leaves us with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

The final outcome is 79480.020811, with a leftover of 6.29e-05.
