We're dividing 18970906 by 637 
The aim is to understand the frequency of 637 in 18970906.

Let's proceed to step 1:
1 divided by 637 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 637

Step 2:
If we divide 18 by 637, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 637

Moving on to step 3:
637 can be fit into 189 0 times, resulting in a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Include the next digit (7) from the dividend after 189, then repeat: 1897 / 637

Let's proceed to step 4:
1897 divided by 637 is 2 with a remainder of 623.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1274 from 1897 leaves us with 623.
Include the next digit (0) from the dividend after 623, then repeat: 6230 / 637

Let's proceed to step 5:
637 goes into 6230 9 times with a remainder of 497.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 5733 from 6230 leaves us with 497.
Append the next digit (9) from the dividend to 497 and continue with: 4979 / 637

Let's proceed to step 6:
4979 divided by 637 is 7 with a remainder of 520.
Use 7 as the next digit of our solution. 
Result so far: 297.0
Subtracting 4459 from 4979 leaves us with 520.
Fetch the next digit (0) from the dividend, attach it to 520 and continue: 5200 / 637

Step 7:
When dividing 5200 by 637, we get 8 with a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 2978.0
Deduct 5096 from 5200 and we're left with 104.
Take the next digit (6) from the dividend and append it to 104, then repeat: 1046 / 637

Advancing to step 8:
1046 divided by 637 is 1 with a remainder of 409.
The number 1 becomes the next digit in our result. 
Result so far: 29781.0
The remainder is 409 after subtracting 637 from 1046.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 9:
637 can be fit into 4090 6 times, resulting in a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 29781.6
The remainder is 268 after subtracting 3822 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 10:
When dividing 2680 by 637, we get 4 with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 29781.64
Deduct 2548 from 2680 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
The number 637 fits into 1320 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 29781.642
If we subtract 1274 from 1320, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
The number 637 fits into 460 0 times, leaving a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 29781.642
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
637 goes into 4600 7 times with a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 29781.64207
If we subtract 4459 from 4600, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 14:
When dividing 1410 by 637, we get 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 29781.642072
Subtract 1274 from 1410 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.

On to step 15:
If we divide 1360 by 637, we get 2 and a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 29781.6420722
If we subtract 1274 from 1360, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 29781.6420722 with a remaining 8.6e-07.
