Let's divide 76579991 by 542
We want to divide 76579991 by 542.

On to step 1:
When dividing 7 by 542, we get 0 with 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.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 542

Step 2:
If we divide 76 by 542, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 542

On to step 3:
When dividing 765 by 542, we get 1 with a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 223 after subtracting 542 from 765.
Grab the next digit (7) from the dividend, add it to 223, then carry on: 2237 / 542

Advancing to step 4:
The number 542 fits into 2237 4 times, leaving a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2168 from 2237 leaves us with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 542

Step 5:
542 can be fit into 699 1 times, resulting in a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 141.0
The remainder is 157 after subtracting 542 from 699.
Append the next digit (9) from the dividend to 157 and continue with: 1579 / 542

Step 6:
If we divide 1579 by 542, we get 2 and a remainder of 495.
Put 2 as the next digit of the answer. 
Result so far: 1412.0
Deduct 1084 from 1579 and we're left with 495.
Grab the next digit (9) from the dividend, add it to 495, then carry on: 4959 / 542

Moving on to step 7:
4959 divided by 542 is 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 14129.0
Subtract 4878 from 4959 to get 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 542

Going ahead to step 8:
When dividing 811 by 542, we get 1 with a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 141291.0
Deduct 542 from 811 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 9:
542 goes into 2690 4 times with a remainder of 522.
Use 4 as the next digit of our solution. 
Result so far: 141291.4
If we subtract 2168 from 2690, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
542 can be fit into 5220 9 times, resulting in a remainder of 342.
Record the quotient 9 as the next digit in the result. 
Result so far: 141291.49
Subtracting 4878 from 5220 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 11:
The number 542 fits into 3420 6 times, leaving a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 141291.496
The remainder is 168 after subtracting 3252 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
542 goes into 1680 3 times with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 141291.4963
The remainder is 54 after subtracting 1626 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
The number 542 fits into 540 0 times, leaving a remainder of 540.
The next digit of our result is 0. 
Result so far: 141291.4963
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 14:
The number 542 fits into 5400 9 times, leaving a remainder of 522.
Use 9 as the next digit of our solution. 
Result so far: 141291.496309
The remainder is 522 after subtracting 4878 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 15:
When dividing 5220 by 542, we get 9 with a remainder of 342.
Record the quotient 9 as the next digit in the result. 
Result so far: 141291.4963099
Subtracting 4878 from 5220 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 141291.4963099, with a leftover of 3.42e-06.
