Let's divide 64101712 by 126
We want to figure out the number of times 64101712 can be divided by 126.

On to step 1:
6 divided by 126 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 126

Moving on to step 2:
The number 126 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 126

Let's proceed to step 3:
126 can be fit into 641 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 630 from 641 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 126

Let's proceed to step 4:
126 can be fit into 110 0 times, resulting in a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 110 after subtracting 0 from 110.
Include the next digit (1) from the dividend after 110, then repeat: 1101 / 126

On to step 5:
126 can be fit into 1101 8 times, resulting in a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 508.0
Subtracting 1008 from 1101 leaves us with 93.
Include the next digit (7) from the dividend after 93, then repeat: 937 / 126

On to step 6:
When dividing 937 by 126, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 5087.0
If we take 882 away from 937, we end up with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 126

Step 7:
551 divided by 126 is 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 50874.0
Deduct 504 from 551 and we're left with 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 126

Moving on to step 8:
When dividing 472 by 126, we get 3 with a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 508743.0
Subtracting 378 from 472 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
940 divided by 126 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 508743.7
Subtract 882 from 940 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
When dividing 580 by 126, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 508743.74
Subtract 504 from 580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
126 goes into 760 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 508743.746
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 126 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 508743.746
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 126 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 508743.74603
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 126, we get 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 508743.746031
The remainder is 94 after subtracting 126 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 15:
The number 126 fits into 940 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 508743.7460317
The remainder is 58 after subtracting 882 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
When dividing 580 by 126, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 508743.74603174
Subtracting 504 from 580 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 508743.74603174 with a remaining 7.6e-08.
