We look at the division of 69448438 by 637 
The aim is to understand the frequency of 637 in 69448438.

On to step 1:
6 divided by 637 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 637

Going ahead to step 2:
The number 637 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 637

Let's proceed to step 3:
When dividing 694 by 637, we get 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 57 after subtracting 637 from 694.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 637

Step 4:
When dividing 574 by 637, we get 0 with a remainder of 574.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 574 and we're left with 574.
Bring next digit (8) of the dividend behind the 574 and repeat the process: 5748 / 637

On to step 5:
If we divide 5748 by 637, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 5733 from 5748 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 637

Advancing to step 6:
637 goes into 154 0 times with a remainder of 154.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
Subtracting 0 from 154 leaves us with 154.
Bring next digit (3) of the dividend behind the 154 and repeat the process: 1543 / 637

On to step 7:
When dividing 1543 by 637, we get 2 with a remainder of 269.
Record the quotient 2 as the next digit in the result. 
Result so far: 10902.0
If we take 1274 away from 1543, we end up with 269.
Take the next digit (8) from the dividend and append it to 269, then repeat: 2698 / 637

On to step 8:
637 goes into 2698 4 times with a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 109024.0
Subtract 2548 from 2698 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
The number 637 fits into 1500 2 times, leaving a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 109024.2
Subtract 1274 from 1500 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
When dividing 2260 by 637, we get 3 with a remainder of 349.
Use 3 as the next digit of our solution. 
Result so far: 109024.23
If we subtract 1911 from 2260, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 11:
If we divide 3490 by 637, we get 5 and a remainder of 305.
The next digit of our result is 5. 
Result so far: 109024.235
Subtract 3185 from 3490 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 12:
3050 divided by 637 is 4 with a remainder of 502.
Write down 4 as next digit of the result. 
Result so far: 109024.2354
Subtract 2548 from 3050 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 13:
637 can be fit into 5020 7 times, resulting in a remainder of 561.
Put 7 as the next digit of the answer. 
Result so far: 109024.23547
Subtract 4459 from 5020 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Let's proceed to step 14:
637 goes into 5610 8 times with a remainder of 514.
Record the quotient 8 as the next digit in the result. 
Result so far: 109024.235478
Subtracting 5096 from 5610 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 15:
The number 637 fits into 5140 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 109024.2354788
The remainder is 44 after subtracting 5096 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 109024.2354788 and a remainder of 4.4e-07.
