We look at the division of 89860274 by 578 
Let's see how many times 578 fits into 89860274.

On to step 1:
The number 578 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 578

On to step 2:
578 can be fit into 89 0 times, resulting in a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 578

On to step 3:
The number 578 fits into 898 1 times, leaving a remainder of 320.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 578 from 898 to get 320.
Append the next digit (6) from the dividend to 320 and continue with: 3206 / 578

Let's proceed to step 4:
When dividing 3206 by 578, we get 5 with a remainder of 316.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2890 from 3206 and we're left with 316.
Bring next digit (0) of the dividend behind the 316 and repeat the process: 3160 / 578

Let's proceed to step 5:
578 goes into 3160 5 times with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we take 2890 away from 3160, we end up with 270.
Grab the next digit (2) from the dividend, add it to 270, then carry on: 2702 / 578

Advancing to step 6:
578 can be fit into 2702 4 times, resulting in a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
Subtracting 2312 from 2702 leaves us with 390.
Append the next digit (7) from the dividend to 390 and continue with: 3907 / 578

Moving on to step 7:
578 can be fit into 3907 6 times, resulting in a remainder of 439.
Use 6 as the next digit of our solution. 
Result so far: 15546.0
If we subtract 3468 from 3907, we get 439.
Include the next digit (4) from the dividend after 439, then repeat: 4394 / 578

On to step 8:
If we divide 4394 by 578, we get 7 and a remainder of 348.
Write down 7 as next digit of the result. 
Result so far: 155467.0
The remainder is 348 after subtracting 4046 from 4394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
578 goes into 3480 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 155467.6
If we take 3468 away from 3480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 578, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 155467.6
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
578 goes into 1200 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 155467.602
Subtracting 1156 from 1200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
If we divide 440 by 578, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 155467.602
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 13:
If we divide 4400 by 578, we get 7 and a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 155467.60207
If we subtract 4046 from 4400, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 14:
578 can be fit into 3540 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 155467.602076
Subtracting 3468 from 3540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
578 goes into 720 1 times with a remainder of 142.
The next digit of our result is 1. 
Result so far: 155467.6020761
Subtract 578 from 720 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 16:
1420 divided by 578 is 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 155467.60207612
Subtract 1156 from 1420 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 155467.60207612 and a remainder of 2.64e-07.
