61875070 ÷ 991 
The aim is to understand the frequency of 991 in 61875070.

Let's proceed to step 1:
991 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 991

Let's proceed to step 2:
If we divide 61 by 991, we get 0 and a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 991

On to step 3:
The number 991 fits into 618 0 times, leaving a remainder of 618.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 618, we get 618.
Grab the next digit (7) from the dividend, add it to 618, then carry on: 6187 / 991

Going ahead to step 4:
The number 991 fits into 6187 6 times, leaving a remainder of 241.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 241 after subtracting 5946 from 6187.
Include the next digit (5) from the dividend after 241, then repeat: 2415 / 991

Moving on to step 5:
The number 991 fits into 2415 2 times, leaving a remainder of 433.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtracting 1982 from 2415 leaves us with 433.
Append the next digit (0) from the dividend to 433 and continue with: 4330 / 991

Advancing to step 6:
991 can be fit into 4330 4 times, resulting in a remainder of 366.
The number 4 becomes the next digit in our result. 
Result so far: 624.0
Deduct 3964 from 4330 and we're left with 366.
Append the next digit (7) from the dividend to 366 and continue with: 3667 / 991

Advancing to step 7:
3667 divided by 991 is 3 with a remainder of 694.
The next digit of our result is 3. 
Result so far: 6243.0
Subtracting 2973 from 3667 leaves us with 694.
Take the next digit (0) from the dividend and append it to 694, then repeat: 6940 / 991

Going ahead to step 8:
991 can be fit into 6940 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 62437.0
Subtract 6937 from 6940 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
991 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 62437.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 991, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 62437.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 62437.0, and the remainder is 0.3.
