We look at the division of 99671305 by 977 
The aim is to understand the frequency of 977 in 99671305.

On to step 1:
9 divided by 977 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 977

On to step 2:
If we divide 99 by 977, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 977

Advancing to step 3:
When dividing 996 by 977, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 977 from 996 to get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 977

Let's proceed to step 4:
When dividing 197 by 977, we get 0 with a remainder of 197.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 197 and we're left with 197.
Append the next digit (1) from the dividend to 197 and continue with: 1971 / 977

Advancing to step 5:
The number 977 fits into 1971 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 1954 away from 1971, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 977

Going ahead to step 6:
173 divided by 977 is 0 with a remainder of 173.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
If we take 0 away from 173, we end up with 173.
Append the next digit (0) from the dividend to 173 and continue with: 1730 / 977

On to step 7:
If we divide 1730 by 977, we get 1 and a remainder of 753.
Put 1 as the next digit of the answer. 
Result so far: 10201.0
Deduct 977 from 1730 and we're left with 753.
Grab the next digit (5) from the dividend, add it to 753, then carry on: 7535 / 977

On to step 8:
977 goes into 7535 7 times with a remainder of 696.
Record the quotient 7 as the next digit in the result. 
Result so far: 102017.0
If we subtract 6839 from 7535, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 9:
When dividing 6960 by 977, we get 7 with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 102017.7
Deduct 6839 from 6960 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 10:
If we divide 1210 by 977, we get 1 and a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 102017.71
The remainder is 233 after subtracting 977 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 11:
977 goes into 2330 2 times with a remainder of 376.
Record the quotient 2 as the next digit in the result. 
Result so far: 102017.712
Deduct 1954 from 2330 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 12:
The number 977 fits into 3760 3 times, leaving a remainder of 829.
Record the quotient 3 as the next digit in the result. 
Result so far: 102017.7123
The remainder is 829 after subtracting 2931 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Step 13:
If we divide 8290 by 977, we get 8 and a remainder of 474.
The number 8 becomes the next digit in our result. 
Result so far: 102017.71238
If we take 7816 away from 8290, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 14:
The number 977 fits into 4740 4 times, leaving a remainder of 832.
Record the quotient 4 as the next digit in the result. 
Result so far: 102017.712384
Deduct 3908 from 4740 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Step 15:
The number 977 fits into 8320 8 times, leaving a remainder of 504.
The next digit of our result is 8. 
Result so far: 102017.7123848
Deduct 7816 from 8320 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 16:
When dividing 5040 by 977, we get 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 102017.71238485
The remainder is 155 after subtracting 4885 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 102017.71238485 with a remaining 1.55e-07.
