Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 599

On to step 2:
When dividing 78 by 599, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 599

Going ahead to step 3:
If we divide 784 by 599, we get 1 and a remainder of 185.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 599 from 784 and we're left with 185.
Append the next digit (5) from the dividend to 185 and continue with: 1855 / 599

Going ahead to step 4:
1855 divided by 599 is 3 with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1797 from 1855 to get 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 599

Going ahead to step 5:
599 goes into 586 0 times with a remainder of 586.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we subtract 0 from 586, we get 586.
Append the next digit (4) from the dividend to 586 and continue with: 5864 / 599

Advancing to step 6:
The number 599 fits into 5864 9 times, leaving a remainder of 473.
The next digit of our result is 9. 
Result so far: 1309.0
If we take 5391 away from 5864, we end up with 473.
Append the next digit (5) from the dividend to 473 and continue with: 4735 / 599

On to step 7:
If we divide 4735 by 599, we get 7 and a remainder of 542.
Record the quotient 7 as the next digit in the result. 
Result so far: 13097.0
Subtracting 4193 from 4735 leaves us with 542.
Include the next digit (8) from the dividend after 542, then repeat: 5428 / 599

Going ahead to step 8:
If we divide 5428 by 599, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 130979.0
Deduct 5391 from 5428 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
599 goes into 370 0 times with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 130979.0
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
When dividing 3700 by 599, we get 6 with a remainder of 106.
The next digit of our result is 6. 
Result so far: 130979.06
If we subtract 3594 from 3700, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
1060 divided by 599 is 1 with a remainder of 461.
The next digit of our result is 1. 
Result so far: 130979.061
If we take 599 away from 1060, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

On to step 12:
599 can be fit into 4610 7 times, resulting in a remainder of 417.
The number 7 becomes the next digit in our result. 
Result so far: 130979.0617
Deduct 4193 from 4610 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 13:
599 goes into 4170 6 times with a remainder of 576.
Use 6 as the next digit of our solution. 
Result so far: 130979.06176
If we subtract 3594 from 4170, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 14:
If we divide 5760 by 599, we get 9 and a remainder of 369.
Record the quotient 9 as the next digit in the result. 
Result so far: 130979.061769
Subtract 5391 from 5760 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 15:
If we divide 3690 by 599, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 130979.0617696
Subtract 3594 from 3690 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
960 divided by 599 is 1 with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 130979.06176961
Subtract 599 from 960 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

After the division, we end up with 130979.06176961 and a remainder of 3.61e-07.
