We look at the division of 75654445 by 991 
The aim is to understand the frequency of 991 in 75654445.

Let's proceed to step 1:
7 divided by 991 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 991

On to step 2:
991 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 991

Let's proceed to step 3:
991 goes into 756 0 times with a remainder of 756.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 756 to get 756.
Grab the next digit (5) from the dividend, add it to 756, then carry on: 7565 / 991

Advancing to step 4:
991 can be fit into 7565 7 times, resulting in a remainder of 628.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6937 from 7565 leaves us with 628.
Include the next digit (4) from the dividend after 628, then repeat: 6284 / 991

Advancing to step 5:
991 can be fit into 6284 6 times, resulting in a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 5946 from 6284 and we're left with 338.
Fetch the next digit (4) from the dividend, attach it to 338 and continue: 3384 / 991

Advancing to step 6:
991 can be fit into 3384 3 times, resulting in a remainder of 411.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we subtract 2973 from 3384, we get 411.
Grab the next digit (4) from the dividend, add it to 411, then carry on: 4114 / 991

Advancing to step 7:
991 goes into 4114 4 times with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 7634.0
If we take 3964 away from 4114, we end up with 150.
Bring next digit (5) of the dividend behind the 150 and repeat the process: 1505 / 991

Going ahead to step 8:
1505 divided by 991 is 1 with a remainder of 514.
Use 1 as the next digit of our solution. 
Result so far: 76341.0
The remainder is 514 after subtracting 991 from 1505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 9:
5140 divided by 991 is 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 76341.5
Deduct 4955 from 5140 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 10:
1850 divided by 991 is 1 with a remainder of 859.
The number 1 becomes the next digit in our result. 
Result so far: 76341.51
If we take 991 away from 1850, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Going ahead to step 11:
The number 991 fits into 8590 8 times, leaving a remainder of 662.
Write down 8 as next digit of the result. 
Result so far: 76341.518
If we take 7928 away from 8590, we end up with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 12:
6620 divided by 991 is 6 with a remainder of 674.
The next digit of our result is 6. 
Result so far: 76341.5186
Subtracting 5946 from 6620 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 13:
991 goes into 6740 6 times with a remainder of 794.
Put 6 as the next digit of the answer. 
Result so far: 76341.51866
Subtract 5946 from 6740 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

The final outcome is 76341.51866, with a leftover of 0.000794.
