We divide 53601751 by 637
The aim is to understand the frequency of 637 in 53601751.

Advancing to step 1:
When dividing 5 by 637, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 637

Moving on to step 2:
53 divided by 637 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 637

Step 3:
When dividing 536 by 637, we get 0 with a remainder of 536.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 536 after subtracting 0 from 536.
Include the next digit (0) from the dividend after 536, then repeat: 5360 / 637

On to step 4:
If we divide 5360 by 637, we get 8 and a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 264 after subtracting 5096 from 5360.
Include the next digit (1) from the dividend after 264, then repeat: 2641 / 637

Let's proceed to step 5:
637 can be fit into 2641 4 times, resulting in a remainder of 93.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 2548 from 2641 leaves us with 93.
Fetch the next digit (7) from the dividend, attach it to 93 and continue: 937 / 637

Advancing to step 6:
937 divided by 637 is 1 with a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
Subtracting 637 from 937 leaves us with 300.
Append the next digit (5) from the dividend to 300 and continue with: 3005 / 637

Advancing to step 7:
If we divide 3005 by 637, we get 4 and a remainder of 457.
Put 4 as the next digit of the answer. 
Result so far: 8414.0
Subtracting 2548 from 3005 leaves us with 457.
Include the next digit (1) from the dividend after 457, then repeat: 4571 / 637

Step 8:
When dividing 4571 by 637, we get 7 with a remainder of 112.
The next digit of our result is 7. 
Result so far: 84147.0
Subtract 4459 from 4571 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
The number 637 fits into 1120 1 times, leaving a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 84147.1
Subtract 637 from 1120 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 10:
The number 637 fits into 4830 7 times, leaving a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 84147.17
Subtracting 4459 from 4830 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 11:
637 can be fit into 3710 5 times, resulting in a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 84147.175
Subtracting 3185 from 3710 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 12:
637 can be fit into 5250 8 times, resulting in a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 84147.1758
If we take 5096 away from 5250, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 13:
If we divide 1540 by 637, we get 2 and a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 84147.17582
The remainder is 266 after subtracting 1274 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 14:
When dividing 2660 by 637, we get 4 with a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 84147.175824
Subtract 2548 from 2660 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
If we divide 1120 by 637, we get 1 and a remainder of 483.
Write down 1 as next digit of the result. 
Result so far: 84147.1758241
Subtracting 637 from 1120 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Step 16:
If we divide 4830 by 637, we get 7 and a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 84147.17582417
Subtract 4459 from 4830 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

After the division, we end up with 84147.17582417 and a remainder of 3.71e-07.
