8580520 ÷ 986 
Our goal is to divide 8580520 by 986.

Step 1:
986 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 986

Let's proceed to step 2:
If we divide 85 by 986, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 986

Going ahead to step 3:
The number 986 fits into 858 0 times, leaving a remainder of 858.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 858, we get 858.
Append the next digit (0) from the dividend to 858 and continue with: 8580 / 986

Going ahead to step 4:
When dividing 8580 by 986, we get 8 with a remainder of 692.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7888 from 8580 to get 692.
Include the next digit (5) from the dividend after 692, then repeat: 6925 / 986

Let's proceed to step 5:
When dividing 6925 by 986, we get 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 6902 from 6925 and we're left with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 986

Step 6:
986 goes into 232 0 times with a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 870.0
Subtract 0 from 232 to get 232.
Fetch the next digit (0) from the dividend, attach it to 232 and continue: 2320 / 986

On to step 7:
986 can be fit into 2320 2 times, resulting in a remainder of 348.
Write down 2 as next digit of the result. 
Result so far: 8702.0
Deduct 1972 from 2320 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 8:
The number 986 fits into 3480 3 times, leaving a remainder of 522.
Write down 3 as next digit of the result. 
Result so far: 8702.3
Deduct 2958 from 3480 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 9:
986 can be fit into 5220 5 times, resulting in a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 8702.35
Subtracting 4930 from 5220 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
When dividing 2900 by 986, we get 2 with a remainder of 928.
The next digit of our result is 2. 
Result so far: 8702.352
Subtracting 1972 from 2900 leaves us with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

On to step 11:
If we divide 9280 by 986, we get 9 and a remainder of 406.
The number 9 becomes the next digit in our result. 
Result so far: 8702.3529
The remainder is 406 after subtracting 8874 from 9280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 12:
When dividing 4060 by 986, we get 4 with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 8702.35294
If we subtract 3944 from 4060, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 13:
When dividing 1160 by 986, we get 1 with a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 8702.352941
Deduct 986 from 1160 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 14:
If we divide 1740 by 986, we get 1 and a remainder of 754.
Record the quotient 1 as the next digit in the result. 
Result so far: 8702.3529411
Subtract 986 from 1740 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

The quotient of the division is 8702.3529411, and the remainder is 7.54e-06.
