We look at the division of 41251120 by 637 
The aim is to understand the frequency of 637 in 41251120.

Advancing to step 1:
When dividing 4 by 637, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 637

On to step 2:
If we divide 41 by 637, we get 0 and a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 637

Step 3:
637 can be fit into 412 0 times, resulting in a remainder of 412.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 412, we end up with 412.
Include the next digit (5) from the dividend after 412, then repeat: 4125 / 637

On to step 4:
637 can be fit into 4125 6 times, resulting in a remainder of 303.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 303 after subtracting 3822 from 4125.
Include the next digit (1) from the dividend after 303, then repeat: 3031 / 637

Step 5:
When dividing 3031 by 637, we get 4 with a remainder of 483.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 483 after subtracting 2548 from 3031.
Grab the next digit (1) from the dividend, add it to 483, then carry on: 4831 / 637

Moving on to step 6:
If we divide 4831 by 637, we get 7 and a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 647.0
If we subtract 4459 from 4831, we get 372.
Include the next digit (2) from the dividend after 372, then repeat: 3722 / 637

On to step 7:
When dividing 3722 by 637, we get 5 with a remainder of 537.
The next digit of our result is 5. 
Result so far: 6475.0
If we subtract 3185 from 3722, we get 537.
Grab the next digit (0) from the dividend, add it to 537, then carry on: 5370 / 637

On to step 8:
637 can be fit into 5370 8 times, resulting in a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 64758.0
The remainder is 274 after subtracting 5096 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
637 can be fit into 2740 4 times, resulting in a remainder of 192.
The next digit of our result is 4. 
Result so far: 64758.4
The remainder is 192 after subtracting 2548 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 10:
1920 divided by 637 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 64758.43
Subtracting 1911 from 1920 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
The number 637 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 64758.43
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
637 goes into 900 1 times with a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 64758.4301
Deduct 637 from 900 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 13:
637 can be fit into 2630 4 times, resulting in a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 64758.43014
If we subtract 2548 from 2630, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 14:
If we divide 820 by 637, we get 1 and a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 64758.430141
The remainder is 183 after subtracting 637 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 15:
The number 637 fits into 1830 2 times, leaving a remainder of 556.
Put 2 as the next digit of the answer. 
Result so far: 64758.4301412
If we subtract 1274 from 1830, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 16:
If we divide 5560 by 637, we get 8 and a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 64758.43014128
The remainder is 464 after subtracting 5096 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The quotient of the division is 64758.43014128, and the remainder is 4.64e-07.
