We look at the division of 76104073 by 977 
The aim is to understand the frequency of 977 in 76104073.

On to step 1:
7 divided by 977 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 977

Going ahead to step 2:
977 can be fit into 76 0 times, resulting in a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 977

Let's proceed to step 3:
When dividing 761 by 977, we get 0 with a remainder of 761.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 761 leaves us with 761.
Append the next digit (0) from the dividend to 761 and continue with: 7610 / 977

Let's proceed to step 4:
977 goes into 7610 7 times with a remainder of 771.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6839 from 7610 leaves us with 771.
Take the next digit (4) from the dividend and append it to 771, then repeat: 7714 / 977

On to step 5:
When dividing 7714 by 977, we get 7 with a remainder of 875.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 6839 from 7714 and we're left with 875.
Include the next digit (0) from the dividend after 875, then repeat: 8750 / 977

On to step 6:
977 goes into 8750 8 times with a remainder of 934.
Use 8 as the next digit of our solution. 
Result so far: 778.0
If we take 7816 away from 8750, we end up with 934.
Grab the next digit (7) from the dividend, add it to 934, then carry on: 9347 / 977

On to step 7:
The number 977 fits into 9347 9 times, leaving a remainder of 554.
The number 9 becomes the next digit in our result. 
Result so far: 7789.0
Deduct 8793 from 9347 and we're left with 554.
Append the next digit (3) from the dividend to 554 and continue with: 5543 / 977

Advancing to step 8:
If we divide 5543 by 977, we get 5 and a remainder of 658.
Record the quotient 5 as the next digit in the result. 
Result so far: 77895.0
Deduct 4885 from 5543 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Let's proceed to step 9:
6580 divided by 977 is 6 with a remainder of 718.
Use 6 as the next digit of our solution. 
Result so far: 77895.6
Subtracting 5862 from 6580 leaves us with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 10:
977 goes into 7180 7 times with a remainder of 341.
The next digit of our result is 7. 
Result so far: 77895.67
Deduct 6839 from 7180 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 11:
977 goes into 3410 3 times with a remainder of 479.
Use 3 as the next digit of our solution. 
Result so far: 77895.673
Deduct 2931 from 3410 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.

Going ahead to step 12:
If we divide 4790 by 977, we get 4 and a remainder of 882.
The next digit of our result is 4. 
Result so far: 77895.6734
If we subtract 3908 from 4790, we get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

On to step 13:
If we divide 8820 by 977, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 77895.67349
Deduct 8793 from 8820 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
270 divided by 977 is 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 77895.67349
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 15:
977 goes into 2700 2 times with a remainder of 746.
Write down 2 as next digit of the result. 
Result so far: 77895.6734902
If we take 1954 away from 2700, we end up with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 16:
977 can be fit into 7460 7 times, resulting in a remainder of 621.
The next digit of our result is 7. 
Result so far: 77895.67349027
Deduct 6839 from 7460 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

The quotient of the division is 77895.67349027, and the remainder is 6.21e-07.
