We look at the division of 86404553 by 178 
Let's see how many times 178 fits into 86404553.

Step 1:
178 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 178

Let's proceed to step 2:
178 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 178

Step 3:
If we divide 864 by 178, we get 4 and a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 712 from 864 to get 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 178

Step 4:
1520 divided by 178 is 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 1424 away from 1520, we end up with 96.
Grab the next digit (4) from the dividend, add it to 96, then carry on: 964 / 178

On to step 5:
If we divide 964 by 178, we get 5 and a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 485.0
If we take 890 away from 964, we end up with 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 178

Let's proceed to step 6:
745 divided by 178 is 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4854.0
If we subtract 712 from 745, we get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 178

Let's proceed to step 7:
When dividing 335 by 178, we get 1 with a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 48541.0
Subtract 178 from 335 to get 157.
Append the next digit (3) from the dividend to 157 and continue with: 1573 / 178

Moving on to step 8:
178 goes into 1573 8 times with a remainder of 149.
The number 8 becomes the next digit in our result. 
Result so far: 485418.0
The remainder is 149 after subtracting 1424 from 1573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
If we divide 1490 by 178, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 485418.8
If we take 1424 away from 1490, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
178 can be fit into 660 3 times, resulting in a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 485418.83
The remainder is 126 after subtracting 534 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 11:
When dividing 1260 by 178, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 485418.837
Subtract 1246 from 1260 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
If we divide 140 by 178, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 485418.837
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
The number 178 fits into 1400 7 times, leaving a remainder of 154.
The next digit of our result is 7. 
Result so far: 485418.83707
The remainder is 154 after subtracting 1246 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 14:
When dividing 1540 by 178, we get 8 with a remainder of 116.
The next digit of our result is 8. 
Result so far: 485418.837078
If we subtract 1424 from 1540, 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.

Moving on to step 15:
178 can be fit into 1160 6 times, resulting in a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 485418.8370786
The remainder is 92 after subtracting 1068 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
When dividing 920 by 178, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 485418.83707865
If we subtract 890 from 920, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 485418.83707865, and the remainder is 3e-08.
