44638611 divided by 637 
The aim is to understand the frequency of 637 in 44638611.

Moving on to step 1:
If we divide 4 by 637, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 637

Going ahead to step 2:
637 can be fit into 44 0 times, resulting in a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 637

On to step 3:
When dividing 446 by 637, we get 0 with a remainder of 446.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 446 after subtracting 0 from 446.
Include the next digit (3) from the dividend after 446, then repeat: 4463 / 637

Let's proceed to step 4:
When dividing 4463 by 637, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4459 from 4463 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 637

Let's proceed to step 5:
If we divide 48 by 637, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 637

Moving on to step 6:
When dividing 486 by 637, we get 0 with a remainder of 486.
The next digit of our result is 0. 
Result so far: 700.0
Subtract 0 from 486 to get 486.
Take the next digit (1) from the dividend and append it to 486, then repeat: 4861 / 637

Advancing to step 7:
If we divide 4861 by 637, we get 7 and a remainder of 402.
Put 7 as the next digit of the answer. 
Result so far: 7007.0
If we take 4459 away from 4861, we end up with 402.
Fetch the next digit (1) from the dividend, attach it to 402 and continue: 4021 / 637

On to step 8:
The number 637 fits into 4021 6 times, leaving a remainder of 199.
The next digit of our result is 6. 
Result so far: 70076.0
If we subtract 3822 from 4021, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 9:
The number 637 fits into 1990 3 times, leaving a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 70076.3
Subtract 1911 from 1990 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
If we divide 790 by 637, we get 1 and a remainder of 153.
The next digit of our result is 1. 
Result so far: 70076.31
If we subtract 637 from 790, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 11:
If we divide 1530 by 637, we get 2 and a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 70076.312
If we subtract 1274 from 1530, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
2560 divided by 637 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 70076.3124
If we subtract 2548 from 2560, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
The number 637 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 70076.3124
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
When dividing 1200 by 637, we get 1 with a remainder of 563.
Use 1 as the next digit of our solution. 
Result so far: 70076.312401
The remainder is 563 after subtracting 637 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 15:
5630 divided by 637 is 8 with a remainder of 534.
The next digit of our result is 8. 
Result so far: 70076.3124018
If we subtract 5096 from 5630, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 16:
The number 637 fits into 5340 8 times, leaving a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 70076.31240188
Deduct 5096 from 5340 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 70076.31240188 with a remainder of 2.44e-07.
