We're dividing 78890043 by 53 
We want to figure out the number of times 78890043 can be divided by 53.

Let's proceed to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 53

On to step 2:
53 goes into 78 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 25 after subtracting 53 from 78.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 53

Step 3:
53 goes into 258 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 212 from 258 to get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 53

Advancing to step 4:
53 can be fit into 469 8 times, resulting in a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 148.0
If we take 424 away from 469, we end up with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 53

Moving on to step 5:
53 goes into 450 8 times with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 1488.0
Deduct 424 from 450 and we're left with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 53

Advancing to step 6:
When dividing 260 by 53, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 14884.0
Deduct 212 from 260 and we're left with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 53

Step 7:
484 divided by 53 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 148849.0
Subtract 477 from 484 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 53

Advancing to step 8:
When dividing 73 by 53, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1488491.0
Subtracting 53 from 73 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.

On to step 9:
200 divided by 53 is 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 1488491.3
Subtracting 159 from 200 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
53 can be fit into 410 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 1488491.37
Subtract 371 from 410 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
53 can be fit into 390 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1488491.377
Subtracting 371 from 390 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 1488491.377, and the remainder is 0.0019.
