Let's divide 45393442 by 939
Let's see how many times 939 fits into 45393442.

Going ahead to step 1:
939 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 939

Advancing to step 2:
45 divided by 939 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 939

Going ahead to step 3:
939 can be fit into 453 0 times, resulting in a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Take the next digit (9) from the dividend and append it to 453, then repeat: 4539 / 939

On to step 4:
4539 divided by 939 is 4 with a remainder of 783.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3756 from 4539 to get 783.
Bring next digit (3) of the dividend behind the 783 and repeat the process: 7833 / 939

Advancing to step 5:
939 goes into 7833 8 times with a remainder of 321.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 7512 from 7833 to get 321.
Grab the next digit (4) from the dividend, add it to 321, then carry on: 3214 / 939

Advancing to step 6:
3214 divided by 939 is 3 with a remainder of 397.
Put 3 as the next digit of the answer. 
Result so far: 483.0
Subtract 2817 from 3214 to get 397.
Take the next digit (4) from the dividend and append it to 397, then repeat: 3974 / 939

Going ahead to step 7:
939 can be fit into 3974 4 times, resulting in a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 4834.0
Deduct 3756 from 3974 and we're left with 218.
Bring next digit (2) of the dividend behind the 218 and repeat the process: 2182 / 939

Step 8:
If we divide 2182 by 939, we get 2 and a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 48342.0
Subtract 1878 from 2182 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
939 can be fit into 3040 3 times, resulting in a remainder of 223.
Record the quotient 3 as the next digit in the result. 
Result so far: 48342.3
If we take 2817 away from 3040, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 10:
939 can be fit into 2230 2 times, resulting in a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 48342.32
Deduct 1878 from 2230 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 11:
When dividing 3520 by 939, we get 3 with a remainder of 703.
Put 3 as the next digit of the answer. 
Result so far: 48342.323
Deduct 2817 from 3520 and we're left with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Going ahead to step 12:
939 goes into 7030 7 times with a remainder of 457.
The number 7 becomes the next digit in our result. 
Result so far: 48342.3237
If we take 6573 away from 7030, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 13:
4570 divided by 939 is 4 with a remainder of 814.
The next digit of our result is 4. 
Result so far: 48342.32374
Subtracting 3756 from 4570 leaves us with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Step 14:
When dividing 8140 by 939, we get 8 with a remainder of 628.
Write down 8 as next digit of the result. 
Result so far: 48342.323748
If we subtract 7512 from 8140, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Advancing to step 15:
939 goes into 6280 6 times with a remainder of 646.
Use 6 as the next digit of our solution. 
Result so far: 48342.3237486
If we take 5634 away from 6280, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Let's proceed to step 16:
939 can be fit into 6460 6 times, resulting in a remainder of 826.
The next digit of our result is 6. 
Result so far: 48342.32374866
The remainder is 826 after subtracting 5634 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

After the division, we end up with 48342.32374866 and a remainder of 8.26e-07.
