887670 divided by 77 
The aim is to understand the frequency of 77 in 887670.

Let's proceed to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 77

Going ahead to step 2:
77 can be fit into 88 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 88, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 77

On to step 3:
When dividing 117 by 77, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 77 from 117, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 77

On to step 4:
77 goes into 406 5 times with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we take 385 away from 406, we end up with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 77

On to step 5:
If we divide 217 by 77, we get 2 and a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 1152.0
If we subtract 154 from 217, we get 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 77

Going ahead to step 6:
If we divide 630 by 77, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 11528.0
Subtract 616 from 630 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 77 is 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 11528.1
If we take 77 away from 140, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
77 can be fit into 630 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 11528.18
If we take 616 away from 630, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
77 goes into 140 1 times with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 11528.181
Subtract 77 from 140 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
77 can be fit into 630 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 11528.1818
Deduct 616 from 630 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
77 can be fit into 140 1 times, resulting in a remainder of 63.
The next digit of our result is 1. 
Result so far: 11528.18181
Subtracting 77 from 140 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
77 goes into 630 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 11528.181818
The remainder is 14 after subtracting 616 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 77, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 11528.1818181
If we take 77 away from 140, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 14:
When dividing 630 by 77, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 11528.18181818
If we subtract 616 from 630, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 11528.18181818 with a remaining 1.4e-08.
