Let's divide 7979643 by 531
We're looking to find how many times 531 goes into 7979643.

On to step 1:
531 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 531

On to step 2:
The number 531 fits into 79 0 times, leaving a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 531

Going ahead to step 3:
531 goes into 797 1 times with a remainder of 266.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 531 from 797, we get 266.
Include the next digit (9) from the dividend after 266, then repeat: 2669 / 531

Advancing to step 4:
531 can be fit into 2669 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2655 from 2669, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 531

Step 5:
146 divided by 531 is 0 with a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Deduct 0 from 146 and we're left with 146.
Append the next digit (4) from the dividend to 146 and continue with: 1464 / 531

Moving on to step 6:
531 can be fit into 1464 2 times, resulting in a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 1502.0
Subtracting 1062 from 1464 leaves us with 402.
Bring next digit (3) of the dividend behind the 402 and repeat the process: 4023 / 531

On to step 7:
531 goes into 4023 7 times with a remainder of 306.
The next digit of our result is 7. 
Result so far: 15027.0
Deduct 3717 from 4023 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 8:
The number 531 fits into 3060 5 times, leaving a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 15027.5
Subtracting 2655 from 3060 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 9:
531 goes into 4050 7 times with a remainder of 333.
Put 7 as the next digit of the answer. 
Result so far: 15027.57
Subtract 3717 from 4050 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 10:
531 can be fit into 3330 6 times, resulting in a remainder of 144.
The next digit of our result is 6. 
Result so far: 15027.576
If we take 3186 away from 3330, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
531 can be fit into 1440 2 times, resulting in a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 15027.5762
If we subtract 1062 from 1440, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 12:
The number 531 fits into 3780 7 times, leaving a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 15027.57627
If we take 3717 away from 3780, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 13:
630 divided by 531 is 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 15027.576271
If we take 531 away from 630, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 14:
When dividing 990 by 531, we get 1 with a remainder of 459.
Put 1 as the next digit of the answer. 
Result so far: 15027.5762711
Deduct 531 from 990 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Our division results in 15027.5762711 with a remaining 4.59e-06.
