66701171 divided by 986 
The aim is to understand the frequency of 986 in 66701171.

Advancing to step 1:
986 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 986

On to step 2:
986 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 986

Advancing to step 3:
The number 986 fits into 667 0 times, leaving a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 667 leaves us with 667.
Append the next digit (0) from the dividend to 667 and continue with: 6670 / 986

On to step 4:
986 goes into 6670 6 times with a remainder of 754.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 754 after subtracting 5916 from 6670.
Include the next digit (1) from the dividend after 754, then repeat: 7541 / 986

Going ahead to step 5:
When dividing 7541 by 986, we get 7 with a remainder of 639.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we subtract 6902 from 7541, we get 639.
Include the next digit (1) from the dividend after 639, then repeat: 6391 / 986

Going ahead to step 6:
986 goes into 6391 6 times with a remainder of 475.
Use 6 as the next digit of our solution. 
Result so far: 676.0
The remainder is 475 after subtracting 5916 from 6391.
Append the next digit (7) from the dividend to 475 and continue with: 4757 / 986

Let's proceed to step 7:
986 can be fit into 4757 4 times, resulting in a remainder of 813.
The number 4 becomes the next digit in our result. 
Result so far: 6764.0
Subtract 3944 from 4757 to get 813.
Grab the next digit (1) from the dividend, add it to 813, then carry on: 8131 / 986

Moving on to step 8:
986 can be fit into 8131 8 times, resulting in a remainder of 243.
The number 8 becomes the next digit in our result. 
Result so far: 67648.0
The remainder is 243 after subtracting 7888 from 8131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 9:
If we divide 2430 by 986, we get 2 and a remainder of 458.
Record the quotient 2 as the next digit in the result. 
Result so far: 67648.2
If we take 1972 away from 2430, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 10:
4580 divided by 986 is 4 with a remainder of 636.
The number 4 becomes the next digit in our result. 
Result so far: 67648.24
Subtract 3944 from 4580 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 11:
986 can be fit into 6360 6 times, resulting in a remainder of 444.
The next digit of our result is 6. 
Result so far: 67648.246
Subtract 5916 from 6360 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 12:
When dividing 4440 by 986, we get 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 67648.2464
Deduct 3944 from 4440 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 13:
986 can be fit into 4960 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 67648.24645
The remainder is 30 after subtracting 4930 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
When dividing 300 by 986, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 67648.24645
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
986 goes into 3000 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 67648.2464503
If we take 2958 away from 3000, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 16:
The number 986 fits into 420 0 times, leaving a remainder of 420.
The next digit of our result is 0. 
Result so far: 67648.2464503
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 67648.2464503, with a leftover of 4.2e-07.
