We look at the division of 98637136 by 671 
The aim is to understand the frequency of 671 in 98637136.

Let's proceed to step 1:
If we divide 9 by 671, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 671

On to step 2:
The number 671 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 671

Let's proceed to step 3:
671 can be fit into 986 1 times, resulting in a remainder of 315.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 671 from 986 and we're left with 315.
Include the next digit (3) from the dividend after 315, then repeat: 3153 / 671

On to step 4:
The number 671 fits into 3153 4 times, leaving a remainder of 469.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2684 from 3153 and we're left with 469.
Fetch the next digit (7) from the dividend, attach it to 469 and continue: 4697 / 671

Let's proceed to step 5:
4697 divided by 671 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Subtract 4697 from 4697 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 671

Going ahead to step 6:
When dividing 1 by 671, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1470.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 671

Let's proceed to step 7:
671 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 14700.0
If we subtract 0 from 13, we get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 671

Step 8:
671 can be fit into 136 0 times, resulting in a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 147000.0
Subtract 0 from 136 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
When dividing 1360 by 671, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 147000.2
Subtracting 1342 from 1360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
If we divide 180 by 671, we get 0 and a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 147000.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
If we divide 1800 by 671, we get 2 and a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 147000.202
The remainder is 458 after subtracting 1342 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 12:
If we divide 4580 by 671, we get 6 and a remainder of 554.
Record the quotient 6 as the next digit in the result. 
Result so far: 147000.2026
Subtract 4026 from 4580 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 13:
5540 divided by 671 is 8 with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 147000.20268
Deduct 5368 from 5540 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 14:
671 can be fit into 1720 2 times, resulting in a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 147000.202682
The remainder is 378 after subtracting 1342 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 15:
When dividing 3780 by 671, we get 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 147000.2026825
Subtracting 3355 from 3780 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 16:
671 goes into 4250 6 times with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 147000.20268256
If we take 4026 away from 4250, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 147000.20268256, with a leftover of 2.24e-07.
