We divide 76450016 by 991
The aim is to understand the frequency of 991 in 76450016.

On to step 1:
When dividing 7 by 991, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 991

Moving on to step 2:
If we divide 76 by 991, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 991

On to step 3:
The number 991 fits into 764 0 times, leaving a remainder of 764.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 764 leaves us with 764.
Fetch the next digit (5) from the dividend, attach it to 764 and continue: 7645 / 991

Moving on to step 4:
The number 991 fits into 7645 7 times, leaving a remainder of 708.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6937 from 7645 leaves us with 708.
Include the next digit (0) from the dividend after 708, then repeat: 7080 / 991

Step 5:
The number 991 fits into 7080 7 times, leaving a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 6937 away from 7080, we end up with 143.
Fetch the next digit (0) from the dividend, attach it to 143 and continue: 1430 / 991

Step 6:
991 goes into 1430 1 times with a remainder of 439.
Record the quotient 1 as the next digit in the result. 
Result so far: 771.0
Subtracting 991 from 1430 leaves us with 439.
Include the next digit (1) from the dividend after 439, then repeat: 4391 / 991

Advancing to step 7:
991 can be fit into 4391 4 times, resulting in a remainder of 427.
Write down 4 as next digit of the result. 
Result so far: 7714.0
Deduct 3964 from 4391 and we're left with 427.
Append the next digit (6) from the dividend to 427 and continue with: 4276 / 991

On to step 8:
991 can be fit into 4276 4 times, resulting in a remainder of 312.
Record the quotient 4 as the next digit in the result. 
Result so far: 77144.0
Subtract 3964 from 4276 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 9:
3120 divided by 991 is 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 77144.3
Subtract 2973 from 3120 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 10:
1470 divided by 991 is 1 with a remainder of 479.
Use 1 as the next digit of our solution. 
Result so far: 77144.31
Deduct 991 from 1470 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 11:
991 goes into 4790 4 times with a remainder of 826.
The number 4 becomes the next digit in our result. 
Result so far: 77144.314
Deduct 3964 from 4790 and we're left with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Going ahead to step 12:
When dividing 8260 by 991, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 77144.3148
Subtracting 7928 from 8260 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 13:
If we divide 3320 by 991, we get 3 and a remainder of 347.
Record the quotient 3 as the next digit in the result. 
Result so far: 77144.31483
Subtracting 2973 from 3320 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 14:
If we divide 3470 by 991, we get 3 and a remainder of 497.
Record the quotient 3 as the next digit in the result. 
Result so far: 77144.314833
Subtracting 2973 from 3470 leaves us with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

After the division, we end up with 77144.314833 and a remainder of 4.97e-05.
