78874754 ÷ 531 
We're looking to find how many times 531 goes into 78874754.

Moving on to step 1:
531 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 531

Step 2:
When dividing 78 by 531, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 531

Going ahead to step 3:
The number 531 fits into 788 1 times, leaving a remainder of 257.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 257 after subtracting 531 from 788.
Fetch the next digit (7) from the dividend, attach it to 257 and continue: 2577 / 531

Step 4:
531 goes into 2577 4 times with a remainder of 453.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2124 from 2577, we get 453.
Grab the next digit (4) from the dividend, add it to 453, then carry on: 4534 / 531

On to step 5:
531 goes into 4534 8 times with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we take 4248 away from 4534, we end up with 286.
Take the next digit (7) from the dividend and append it to 286, then repeat: 2867 / 531

Advancing to step 6:
When dividing 2867 by 531, we get 5 with a remainder of 212.
The number 5 becomes the next digit in our result. 
Result so far: 1485.0
Subtract 2655 from 2867 to get 212.
Include the next digit (5) from the dividend after 212, then repeat: 2125 / 531

On to step 7:
531 goes into 2125 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14854.0
Deduct 2124 from 2125 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 531

On to step 8:
The number 531 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 148540.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
531 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 148540.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
531 can be fit into 1400 2 times, resulting in a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 148540.02
The remainder is 338 after subtracting 1062 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 11:
3380 divided by 531 is 6 with a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 148540.026
If we subtract 3186 from 3380, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 12:
1940 divided by 531 is 3 with a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 148540.0263
Subtracting 1593 from 1940 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 13:
531 goes into 3470 6 times with a remainder of 284.
Write down 6 as next digit of the result. 
Result so far: 148540.02636
If we subtract 3186 from 3470, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 14:
2840 divided by 531 is 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 148540.026365
If we take 2655 away from 2840, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 15:
531 can be fit into 1850 3 times, resulting in a remainder of 257.
The next digit of our result is 3. 
Result so far: 148540.0263653
Subtracting 1593 from 1850 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 16:
When dividing 2570 by 531, we get 4 with a remainder of 446.
Use 4 as the next digit of our solution. 
Result so far: 148540.02636534
Deduct 2124 from 2570 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The quotient of the division is 148540.02636534, and the remainder is 4.46e-07.
