We're dividing 45139440 by 52 
We want to divide 45139440 by 52.

Step 1:
4 divided by 52 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 52

Advancing to step 2:
When dividing 45 by 52, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 52

Step 3:
52 goes into 451 8 times with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 416 from 451 leaves us with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 52

On to step 4:
If we divide 353 by 52, we get 6 and a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 312 from 353, we get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 52

Step 5:
52 goes into 419 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 868.0
Subtract 416 from 419 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 52

On to step 6:
The number 52 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 8680.0
Subtract 0 from 34 to get 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 52

Moving on to step 7:
52 goes into 344 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 86806.0
Subtract 312 from 344 to get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 52

Moving on to step 8:
52 can be fit into 320 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 868066.0
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 52, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 868066.1
The remainder is 28 after subtracting 52 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 52 fits into 280 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 868066.15
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 52 fits into 200 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 868066.153
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
If we divide 440 by 52, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 868066.1538
Deduct 416 from 440 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 52, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 868066.15384
Deduct 208 from 240 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
52 can be fit into 320 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 868066.153846
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
52 goes into 80 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 868066.1538461
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
The number 52 fits into 280 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 868066.15384615
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 868066.15384615 with a remaining 2e-08.
