We look at the division of 89612142 by 586 
We want to figure out the number of times 89612142 can be divided by 586.

On to step 1:
586 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 586

On to step 2:
89 divided by 586 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 586

Moving on to step 3:
896 divided by 586 is 1 with a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 586 from 896 and we're left with 310.
Take the next digit (1) from the dividend and append it to 310, then repeat: 3101 / 586

Moving on to step 4:
If we divide 3101 by 586, we get 5 and a remainder of 171.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2930 from 3101 and we're left with 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 586

Advancing to step 5:
If we divide 1712 by 586, we get 2 and a remainder of 540.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtracting 1172 from 1712 leaves us with 540.
Bring next digit (1) of the dividend behind the 540 and repeat the process: 5401 / 586

Moving on to step 6:
The number 586 fits into 5401 9 times, leaving a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 1529.0
Subtracting 5274 from 5401 leaves us with 127.
Bring next digit (4) of the dividend behind the 127 and repeat the process: 1274 / 586

Advancing to step 7:
586 goes into 1274 2 times with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 15292.0
Subtract 1172 from 1274 to get 102.
Include the next digit (2) from the dividend after 102, then repeat: 1022 / 586

Let's proceed to step 8:
When dividing 1022 by 586, we get 1 with a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 152921.0
If we subtract 586 from 1022, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
The number 586 fits into 4360 7 times, leaving a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 152921.7
If we take 4102 away from 4360, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
When dividing 2580 by 586, we get 4 with a remainder of 236.
The next digit of our result is 4. 
Result so far: 152921.74
The remainder is 236 after subtracting 2344 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 11:
If we divide 2360 by 586, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 152921.744
If we take 2344 away from 2360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 152921.744 and a remainder of 0.0016.
