Let's divide 85978430 by 586
Our goal is to divide 85978430 by 586.

Going ahead to step 1:
586 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 586

On to step 2:
When dividing 85 by 586, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 586

On to step 3:
The number 586 fits into 859 1 times, leaving a remainder of 273.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 586 from 859 to get 273.
Take the next digit (7) from the dividend and append it to 273, then repeat: 2737 / 586

Moving on to step 4:
586 can be fit into 2737 4 times, resulting in a remainder of 393.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2344 away from 2737, we end up with 393.
Take the next digit (8) from the dividend and append it to 393, then repeat: 3938 / 586

On to step 5:
The number 586 fits into 3938 6 times, leaving a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we subtract 3516 from 3938, we get 422.
Append the next digit (4) from the dividend to 422 and continue with: 4224 / 586

Advancing to step 6:
586 goes into 4224 7 times with a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 1467.0
Subtract 4102 from 4224 to get 122.
Fetch the next digit (3) from the dividend, attach it to 122 and continue: 1223 / 586

Step 7:
If we divide 1223 by 586, we get 2 and a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 14672.0
Subtracting 1172 from 1223 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 586

Advancing to step 8:
586 can be fit into 510 0 times, resulting in a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 146720.0
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 9:
If we divide 5100 by 586, we get 8 and a remainder of 412.
Put 8 as the next digit of the answer. 
Result so far: 146720.8
Subtract 4688 from 5100 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 10:
When dividing 4120 by 586, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 146720.87
If we subtract 4102 from 4120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
The number 586 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 146720.87
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
586 goes into 1800 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 146720.8703
Deduct 1758 from 1800 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
If we divide 420 by 586, we get 0 and a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 146720.8703
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
4200 divided by 586 is 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 146720.870307
Deduct 4102 from 4200 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 15:
586 goes into 980 1 times with a remainder of 394.
Put 1 as the next digit of the answer. 
Result so far: 146720.8703071
Deduct 586 from 980 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 16:
When dividing 3940 by 586, we get 6 with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 146720.87030716
If we subtract 3516 from 3940, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 146720.87030716, with a leftover of 4.24e-07.
