Let's divide 87143481 by 803
Our goal is to divide 87143481 by 803.

Moving on to step 1:
803 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 803

On to step 2:
803 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 803

On to step 3:
803 can be fit into 871 1 times, resulting in a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 803 from 871 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 803

On to step 4:
The number 803 fits into 684 0 times, leaving a remainder of 684.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 684, we end up with 684.
Bring next digit (3) of the dividend behind the 684 and repeat the process: 6843 / 803

Advancing to step 5:
803 can be fit into 6843 8 times, resulting in a remainder of 419.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 6424 from 6843 and we're left with 419.
Take the next digit (4) from the dividend and append it to 419, then repeat: 4194 / 803

Going ahead to step 6:
When dividing 4194 by 803, we get 5 with a remainder of 179.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Deduct 4015 from 4194 and we're left with 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 803

Let's proceed to step 7:
1798 divided by 803 is 2 with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 10852.0
If we subtract 1606 from 1798, we get 192.
Grab the next digit (1) from the dividend, add it to 192, then carry on: 1921 / 803

Moving on to step 8:
If we divide 1921 by 803, we get 2 and a remainder of 315.
The number 2 becomes the next digit in our result. 
Result so far: 108522.0
If we subtract 1606 from 1921, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
803 goes into 3150 3 times with a remainder of 741.
Put 3 as the next digit of the answer. 
Result so far: 108522.3
Subtract 2409 from 3150 to get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Let's proceed to step 10:
803 can be fit into 7410 9 times, resulting in a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 108522.39
The remainder is 183 after subtracting 7227 from 7410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 11:
If we divide 1830 by 803, we get 2 and a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 108522.392
The remainder is 224 after subtracting 1606 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
When dividing 2240 by 803, we get 2 with a remainder of 634.
Put 2 as the next digit of the answer. 
Result so far: 108522.3922
Subtracting 1606 from 2240 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

After the division, we end up with 108522.3922 and a remainder of 0.00634.
