We divide 87124158 by 771
The aim is to understand the frequency of 771 in 87124158.

On to step 1:
If we divide 8 by 771, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 771

Moving on to step 2:
The number 771 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 771

Advancing to step 3:
If we divide 871 by 771, we get 1 and a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 771 from 871 leaves us with 100.
Bring next digit (2) of the dividend behind the 100 and repeat the process: 1002 / 771

Going ahead to step 4:
771 goes into 1002 1 times with a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 231 after subtracting 771 from 1002.
Include the next digit (4) from the dividend after 231, then repeat: 2314 / 771

Moving on to step 5:
771 can be fit into 2314 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 2313 from 2314 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 771

Advancing to step 6:
When dividing 11 by 771, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 1130.0
Subtract 0 from 11 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 771

Let's proceed to step 7:
771 can be fit into 115 0 times, resulting in a remainder of 115.
The next digit of our result is 0. 
Result so far: 11300.0
If we subtract 0 from 115, we get 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 771

Advancing to step 8:
771 goes into 1158 1 times with a remainder of 387.
The number 1 becomes the next digit in our result. 
Result so far: 113001.0
If we take 771 away from 1158, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 9:
When dividing 3870 by 771, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 113001.5
If we take 3855 away from 3870, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
771 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 113001.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
When dividing 1500 by 771, we get 1 with a remainder of 729.
Use 1 as the next digit of our solution. 
Result so far: 113001.501
If we take 771 away from 1500, we end up with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

On to step 12:
771 can be fit into 7290 9 times, resulting in a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 113001.5019
Deduct 6939 from 7290 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
771 goes into 3510 4 times with a remainder of 426.
Record the quotient 4 as the next digit in the result. 
Result so far: 113001.50194
Subtract 3084 from 3510 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 14:
When dividing 4260 by 771, we get 5 with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 113001.501945
Subtracting 3855 from 4260 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 15:
4050 divided by 771 is 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 113001.5019455
If we subtract 3855 from 4050, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Our division results in 113001.5019455 with a remaining 1.95e-06.
