We look at the division of 16439732 by 977 
The aim is to understand the frequency of 977 in 16439732.

Advancing to step 1:
When dividing 1 by 977, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 977

Going ahead to step 2:
If we divide 16 by 977, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 977

On to step 3:
977 can be fit into 164 0 times, resulting in a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 977

Step 4:
The number 977 fits into 1643 1 times, leaving a remainder of 666.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 977 from 1643 to get 666.
Take the next digit (9) from the dividend and append it to 666, then repeat: 6669 / 977

Advancing to step 5:
When dividing 6669 by 977, we get 6 with a remainder of 807.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 5862 from 6669 leaves us with 807.
Include the next digit (7) from the dividend after 807, then repeat: 8077 / 977

Step 6:
977 can be fit into 8077 8 times, resulting in a remainder of 261.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtracting 7816 from 8077 leaves us with 261.
Take the next digit (3) from the dividend and append it to 261, then repeat: 2613 / 977

Let's proceed to step 7:
977 can be fit into 2613 2 times, resulting in a remainder of 659.
Put 2 as the next digit of the answer. 
Result so far: 1682.0
If we subtract 1954 from 2613, we get 659.
Take the next digit (2) from the dividend and append it to 659, then repeat: 6592 / 977

Let's proceed to step 8:
6592 divided by 977 is 6 with a remainder of 730.
The number 6 becomes the next digit in our result. 
Result so far: 16826.0
Subtracting 5862 from 6592 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 9:
If we divide 7300 by 977, we get 7 and a remainder of 461.
Put 7 as the next digit of the answer. 
Result so far: 16826.7
If we subtract 6839 from 7300, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

On to step 10:
4610 divided by 977 is 4 with a remainder of 702.
Write down 4 as next digit of the result. 
Result so far: 16826.74
Subtracting 3908 from 4610 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Moving on to step 11:
977 can be fit into 7020 7 times, resulting in a remainder of 181.
The number 7 becomes the next digit in our result. 
Result so far: 16826.747
The remainder is 181 after subtracting 6839 from 7020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 12:
If we divide 1810 by 977, we get 1 and a remainder of 833.
Record the quotient 1 as the next digit in the result. 
Result so far: 16826.7471
Subtract 977 from 1810 to get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Let's proceed to step 13:
If we divide 8330 by 977, we get 8 and a remainder of 514.
Use 8 as the next digit of our solution. 
Result so far: 16826.74718
If we subtract 7816 from 8330, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 14:
977 goes into 5140 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 16826.747185
Deduct 4885 from 5140 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 15:
2550 divided by 977 is 2 with a remainder of 596.
Put 2 as the next digit of the answer. 
Result so far: 16826.7471852
Deduct 1954 from 2550 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 16:
5960 divided by 977 is 6 with a remainder of 98.
The next digit of our result is 6. 
Result so far: 16826.74718526
If we subtract 5862 from 5960, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 16826.74718526 and a remainder of 9.8e-08.
