Let's divide 54312690 by 709
We're looking to find how many times 709 goes into 54312690.

Going ahead to step 1:
709 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 709

Going ahead to step 2:
If we divide 54 by 709, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 709

Let's proceed to step 3:
If we divide 543 by 709, we get 0 and a remainder of 543.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 543 after subtracting 0 from 543.
Include the next digit (1) from the dividend after 543, then repeat: 5431 / 709

On to step 4:
709 goes into 5431 7 times with a remainder of 468.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 4963 from 5431 to get 468.
Grab the next digit (2) from the dividend, add it to 468, then carry on: 4682 / 709

Moving on to step 5:
709 can be fit into 4682 6 times, resulting in a remainder of 428.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 4254 from 4682 leaves us with 428.
Take the next digit (6) from the dividend and append it to 428, then repeat: 4286 / 709

Moving on to step 6:
709 goes into 4286 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 766.0
If we take 4254 away from 4286, we end up with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 709

Going ahead to step 7:
When dividing 329 by 709, we get 0 with a remainder of 329.
Put 0 as the next digit of the answer. 
Result so far: 7660.0
If we subtract 0 from 329, we get 329.
Take the next digit (0) from the dividend and append it to 329, then repeat: 3290 / 709

On to step 8:
If we divide 3290 by 709, we get 4 and a remainder of 454.
Write down 4 as next digit of the result. 
Result so far: 76604.0
If we subtract 2836 from 3290, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 9:
4540 divided by 709 is 6 with a remainder of 286.
The next digit of our result is 6. 
Result so far: 76604.6
If we take 4254 away from 4540, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
709 goes into 2860 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 76604.64
Deduct 2836 from 2860 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.

Step 11:
240 divided by 709 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 76604.64
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
709 can be fit into 2400 3 times, resulting in a remainder of 273.
Record the quotient 3 as the next digit in the result. 
Result so far: 76604.6403
Subtracting 2127 from 2400 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 13:
2730 divided by 709 is 3 with a remainder of 603.
The number 3 becomes the next digit in our result. 
Result so far: 76604.64033
If we subtract 2127 from 2730, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

The quotient of the division is 76604.64033, and the remainder is 0.000603.
