We look at the division of 87571043 by 767 
The aim is to understand the frequency of 767 in 87571043.

On to step 1:
The number 767 fits into 8 0 times, leaving 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.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 767

Advancing to step 2:
If we divide 87 by 767, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (5) from the dividend after 87, then repeat: 875 / 767

Step 3:
The number 767 fits into 875 1 times, leaving a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 108 after subtracting 767 from 875.
Append the next digit (7) from the dividend to 108 and continue with: 1087 / 767

Going ahead to step 4:
When dividing 1087 by 767, we get 1 with a remainder of 320.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 320 after subtracting 767 from 1087.
Fetch the next digit (1) from the dividend, attach it to 320 and continue: 3201 / 767

Advancing to step 5:
When dividing 3201 by 767, we get 4 with a remainder of 133.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 3068 from 3201 leaves us with 133.
Include the next digit (0) from the dividend after 133, then repeat: 1330 / 767

On to step 6:
767 goes into 1330 1 times with a remainder of 563.
Write down 1 as next digit of the result. 
Result so far: 1141.0
Subtracting 767 from 1330 leaves us with 563.
Bring next digit (4) of the dividend behind the 563 and repeat the process: 5634 / 767

Step 7:
When dividing 5634 by 767, we get 7 with a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 11417.0
Deduct 5369 from 5634 and we're left with 265.
Fetch the next digit (3) from the dividend, attach it to 265 and continue: 2653 / 767

Let's proceed to step 8:
The number 767 fits into 2653 3 times, leaving a remainder of 352.
Use 3 as the next digit of our solution. 
Result so far: 114173.0
Subtract 2301 from 2653 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 9:
The number 767 fits into 3520 4 times, leaving a remainder of 452.
Record the quotient 4 as the next digit in the result. 
Result so far: 114173.4
The remainder is 452 after subtracting 3068 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 10:
4520 divided by 767 is 5 with a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 114173.45
Subtracting 3835 from 4520 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 11:
767 can be fit into 6850 8 times, resulting in a remainder of 714.
Put 8 as the next digit of the answer. 
Result so far: 114173.458
Deduct 6136 from 6850 and we're left with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

On to step 12:
767 can be fit into 7140 9 times, resulting in a remainder of 237.
The next digit of our result is 9. 
Result so far: 114173.4589
The remainder is 237 after subtracting 6903 from 7140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 13:
The number 767 fits into 2370 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 114173.45893
The remainder is 69 after subtracting 2301 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
767 can be fit into 690 0 times, resulting in a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 114173.45893
Subtract 0 from 690 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 15:
767 can be fit into 6900 8 times, resulting in a remainder of 764.
Put 8 as the next digit of the answer. 
Result so far: 114173.4589308
If we take 6136 away from 6900, we end up with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 16:
When dividing 7640 by 767, we get 9 with a remainder of 737.
The next digit of our result is 9. 
Result so far: 114173.45893089
If we subtract 6903 from 7640, we get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

After the division, we end up with 114173.45893089 and a remainder of 7.37e-07.
