We're dividing 61275900 by 504 
We want to figure out the number of times 61275900 can be divided by 504.

Step 1:
If we divide 6 by 504, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 504

Going ahead to step 2:
504 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 504

Going ahead to step 3:
When dividing 612 by 504, we get 1 with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 504 away from 612, we end up with 108.
Grab the next digit (7) from the dividend, add it to 108, then carry on: 1087 / 504

Moving on to step 4:
When dividing 1087 by 504, we get 2 with a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1008 from 1087 and we're left with 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 504

Step 5:
The number 504 fits into 795 1 times, leaving a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtracting 504 from 795 leaves us with 291.
Fetch the next digit (9) from the dividend, attach it to 291 and continue: 2919 / 504

Moving on to step 6:
When dividing 2919 by 504, we get 5 with a remainder of 399.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
If we take 2520 away from 2919, we end up with 399.
Fetch the next digit (0) from the dividend, attach it to 399 and continue: 3990 / 504

On to step 7:
When dividing 3990 by 504, we get 7 with a remainder of 462.
Write down 7 as next digit of the result. 
Result so far: 12157.0
If we take 3528 away from 3990, we end up with 462.
Fetch the next digit (0) from the dividend, attach it to 462 and continue: 4620 / 504

Advancing to step 8:
4620 divided by 504 is 9 with a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 121579.0
Subtract 4536 from 4620 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
504 goes into 840 1 times with a remainder of 336.
Use 1 as the next digit of our solution. 
Result so far: 121579.1
Subtracting 504 from 840 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
504 can be fit into 3360 6 times, resulting in a remainder of 336.
The next digit of our result is 6. 
Result so far: 121579.16
Deduct 3024 from 3360 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 11:
504 can be fit into 3360 6 times, resulting in a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 121579.166
Subtract 3024 from 3360 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 121579.166 and a remainder of 0.0336.
