We're dividing 39910121 by 506 
We're looking to find how many times 506 goes into 39910121.

Going ahead to step 1:
The number 506 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 506

On to step 2:
39 divided by 506 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 506

Let's proceed to step 3:
If we divide 399 by 506, we get 0 and a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 399 and we're left with 399.
Include the next digit (1) from the dividend after 399, then repeat: 3991 / 506

Moving on to step 4:
The number 506 fits into 3991 7 times, leaving a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 3542 from 3991, we get 449.
Append the next digit (0) from the dividend to 449 and continue with: 4490 / 506

Step 5:
If we divide 4490 by 506, we get 8 and a remainder of 442.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 4048 from 4490 to get 442.
Grab the next digit (1) from the dividend, add it to 442, then carry on: 4421 / 506

Moving on to step 6:
506 can be fit into 4421 8 times, resulting in a remainder of 373.
Put 8 as the next digit of the answer. 
Result so far: 788.0
The remainder is 373 after subtracting 4048 from 4421.
Grab the next digit (2) from the dividend, add it to 373, then carry on: 3732 / 506

On to step 7:
506 can be fit into 3732 7 times, resulting in a remainder of 190.
Put 7 as the next digit of the answer. 
Result so far: 7887.0
Subtracting 3542 from 3732 leaves us with 190.
Grab the next digit (1) from the dividend, add it to 190, then carry on: 1901 / 506

Step 8:
If we divide 1901 by 506, we get 3 and a remainder of 383.
Record the quotient 3 as the next digit in the result. 
Result so far: 78873.0
If we take 1518 away from 1901, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 9:
If we divide 3830 by 506, we get 7 and a remainder of 288.
Put 7 as the next digit of the answer. 
Result so far: 78873.7
Subtract 3542 from 3830 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 10:
506 can be fit into 2880 5 times, resulting in a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 78873.75
If we subtract 2530 from 2880, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
The number 506 fits into 3500 6 times, leaving a remainder of 464.
The next digit of our result is 6. 
Result so far: 78873.756
Subtracting 3036 from 3500 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 12:
When dividing 4640 by 506, we get 9 with a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 78873.7569
Deduct 4554 from 4640 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
If we divide 860 by 506, we get 1 and a remainder of 354.
The next digit of our result is 1. 
Result so far: 78873.75691
The remainder is 354 after subtracting 506 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 14:
506 can be fit into 3540 6 times, resulting in a remainder of 504.
The next digit of our result is 6. 
Result so far: 78873.756916
If we subtract 3036 from 3540, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 15:
When dividing 5040 by 506, we get 9 with a remainder of 486.
Put 9 as the next digit of the answer. 
Result so far: 78873.7569169
Subtracting 4554 from 5040 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 16:
When dividing 4860 by 506, we get 9 with a remainder of 306.
Put 9 as the next digit of the answer. 
Result so far: 78873.75691699
Subtract 4554 from 4860 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The quotient of the division is 78873.75691699, and the remainder is 3.06e-07.
