Let's divide 78495867 by 289
Our goal is to divide 78495867 by 289.

On to step 1:
289 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 289

Advancing to step 2:
78 divided by 289 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 289

Step 3:
When dividing 784 by 289, we get 2 with a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 578 from 784 and we're left with 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 289

Step 4:
289 goes into 2069 7 times with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 2023 from 2069, we get 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 289

Moving on to step 5:
289 goes into 465 1 times with a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 271.0
The remainder is 176 after subtracting 289 from 465.
Fetch the next digit (8) from the dividend, attach it to 176 and continue: 1768 / 289

Step 6:
289 can be fit into 1768 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 2716.0
Deduct 1734 from 1768 and we're left with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 289

On to step 7:
When dividing 346 by 289, we get 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 27161.0
Subtracting 289 from 346 leaves us with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 289

Advancing to step 8:
289 can be fit into 577 1 times, resulting in a remainder of 288.
Write down 1 as next digit of the result. 
Result so far: 271611.0
Subtract 289 from 577 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 9:
2880 divided by 289 is 9 with a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 271611.9
If we take 2601 away from 2880, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 10:
The number 289 fits into 2790 9 times, leaving a remainder of 189.
Write down 9 as next digit of the result. 
Result so far: 271611.99
Subtract 2601 from 2790 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The quotient of the division is 271611.99, and the remainder is 0.189.
