Let's divide 78201592 by 905
We're looking to find how many times 905 goes into 78201592.

Moving on to step 1:
905 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 905

Step 2:
When dividing 78 by 905, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 905

On to step 3:
905 can be fit into 782 0 times, resulting in a remainder of 782.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 782, we get 782.
Bring next digit (0) of the dividend behind the 782 and repeat the process: 7820 / 905

Advancing to step 4:
If we divide 7820 by 905, we get 8 and a remainder of 580.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7240 from 7820 and we're left with 580.
Grab the next digit (1) from the dividend, add it to 580, then carry on: 5801 / 905

On to step 5:
When dividing 5801 by 905, we get 6 with a remainder of 371.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 5430 from 5801, we get 371.
Fetch the next digit (5) from the dividend, attach it to 371 and continue: 3715 / 905

Step 6:
The number 905 fits into 3715 4 times, leaving a remainder of 95.
Record the quotient 4 as the next digit in the result. 
Result so far: 864.0
If we take 3620 away from 3715, we end up with 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 905

Moving on to step 7:
905 can be fit into 959 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 8641.0
Subtracting 905 from 959 leaves us with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 905

Advancing to step 8:
542 divided by 905 is 0 with a remainder of 542.
Put 0 as the next digit of the answer. 
Result so far: 86410.0
If we subtract 0 from 542, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 9:
905 can be fit into 5420 5 times, resulting in a remainder of 895.
Record the quotient 5 as the next digit in the result. 
Result so far: 86410.5
Subtract 4525 from 5420 to get 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

Going ahead to step 10:
When dividing 8950 by 905, we get 9 with a remainder of 805.
The next digit of our result is 9. 
Result so far: 86410.59
The remainder is 805 after subtracting 8145 from 8950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Going ahead to step 11:
If we divide 8050 by 905, we get 8 and a remainder of 810.
Use 8 as the next digit of our solution. 
Result so far: 86410.598
Subtract 7240 from 8050 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 12:
If we divide 8100 by 905, we get 8 and a remainder of 860.
Put 8 as the next digit of the answer. 
Result so far: 86410.5988
The remainder is 860 after subtracting 7240 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final result is 86410.5988 with a remainder of 0.0086.
