43775050 ÷ 637 
The aim is to understand the frequency of 637 in 43775050.

Step 1:
4 divided by 637 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 637

Step 2:
637 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 637

Moving on to step 3:
437 divided by 637 is 0 with a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 437 and we're left with 437.
Take the next digit (7) from the dividend and append it to 437, then repeat: 4377 / 637

Let's proceed to step 4:
637 can be fit into 4377 6 times, resulting in a remainder of 555.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3822 from 4377 leaves us with 555.
Fetch the next digit (5) from the dividend, attach it to 555 and continue: 5555 / 637

Going ahead to step 5:
If we divide 5555 by 637, we get 8 and a remainder of 459.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
The remainder is 459 after subtracting 5096 from 5555.
Take the next digit (0) from the dividend and append it to 459, then repeat: 4590 / 637

Let's proceed to step 6:
If we divide 4590 by 637, we get 7 and a remainder of 131.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
Subtract 4459 from 4590 to get 131.
Fetch the next digit (5) from the dividend, attach it to 131 and continue: 1315 / 637

Advancing to step 7:
The number 637 fits into 1315 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 6872.0
Deduct 1274 from 1315 and we're left with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 637

Advancing to step 8:
410 divided by 637 is 0 with a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 68720.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 9:
637 goes into 4100 6 times with a remainder of 278.
Use 6 as the next digit of our solution. 
Result so far: 68720.6
Subtract 3822 from 4100 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 10:
2780 divided by 637 is 4 with a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 68720.64
Subtracting 2548 from 2780 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 11:
637 can be fit into 2320 3 times, resulting in a remainder of 409.
Put 3 as the next digit of the answer. 
Result so far: 68720.643
The remainder is 409 after subtracting 1911 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 12:
When dividing 4090 by 637, we get 6 with a remainder of 268.
Use 6 as the next digit of our solution. 
Result so far: 68720.6436
Deduct 3822 from 4090 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 13:
If we divide 2680 by 637, we get 4 and a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 68720.64364
Subtract 2548 from 2680 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
637 can be fit into 1320 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 68720.643642
Deduct 1274 from 1320 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
637 goes into 460 0 times with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 68720.643642
If we take 0 away from 460, we end up 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.

Moving on to step 16:
The number 637 fits into 4600 7 times, leaving a remainder of 141.
The number 7 becomes the next digit in our result. 
Result so far: 68720.64364207
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.

In conclusion, the division gives 68720.64364207 with a balance of 1.41e-07.
