Let's divide 89231690 by 800
Our goal is to divide 89231690 by 800.

Moving on to step 1:
When dividing 8 by 800, we get 0 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 / 800

Moving on to step 2:
800 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 800

On to step 3:
892 divided by 800 is 1 with a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 800 from 892, we get 92.
Append the next digit (3) from the dividend to 92 and continue with: 923 / 800

On to step 4:
If we divide 923 by 800, we get 1 and a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 800 from 923 and we're left with 123.
Grab the next digit (1) from the dividend, add it to 123, then carry on: 1231 / 800

On to step 5:
If we divide 1231 by 800, we get 1 and a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtract 800 from 1231 to get 431.
Include the next digit (6) from the dividend after 431, then repeat: 4316 / 800

Moving on to step 6:
The number 800 fits into 4316 5 times, leaving a remainder of 316.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
Deduct 4000 from 4316 and we're left with 316.
Grab the next digit (9) from the dividend, add it to 316, then carry on: 3169 / 800

Going ahead to step 7:
When dividing 3169 by 800, we get 3 with a remainder of 769.
Write down 3 as next digit of the result. 
Result so far: 11153.0
Subtracting 2400 from 3169 leaves us with 769.
Bring next digit (0) of the dividend behind the 769 and repeat the process: 7690 / 800

Let's proceed to step 8:
When dividing 7690 by 800, we get 9 with a remainder of 490.
Record the quotient 9 as the next digit in the result. 
Result so far: 111539.0
Subtract 7200 from 7690 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 9:
800 can be fit into 4900 6 times, resulting in a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 111539.6
If we take 4800 away from 4900, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 800 fits into 1000 1 times, leaving a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 111539.61
Deduct 800 from 1000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
800 goes into 2000 2 times with a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 111539.612
If we take 1600 away from 2000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 800, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 111539.6125
Subtract 4000 from 4000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 111539.6125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 111539.6125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 111539.6125, with a leftover of 0.0.
