We look at the division of 78099260 by 905 
We're looking to find how many times 905 goes into 78099260.

Let's proceed to step 1:
7 divided by 905 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 905

Moving on to step 2:
78 divided by 905 is 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.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 905

Step 3:
When dividing 780 by 905, we get 0 with a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 780, we get 780.
Append the next digit (9) from the dividend to 780 and continue with: 7809 / 905

On to step 4:
905 goes into 7809 8 times with a remainder of 569.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7240 from 7809 and we're left with 569.
Fetch the next digit (9) from the dividend, attach it to 569 and continue: 5699 / 905

Advancing to step 5:
If we divide 5699 by 905, we get 6 and a remainder of 269.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 269 after subtracting 5430 from 5699.
Fetch the next digit (2) from the dividend, attach it to 269 and continue: 2692 / 905

Going ahead to step 6:
2692 divided by 905 is 2 with a remainder of 882.
The next digit of our result is 2. 
Result so far: 862.0
Subtract 1810 from 2692 to get 882.
Take the next digit (6) from the dividend and append it to 882, then repeat: 8826 / 905

Let's proceed to step 7:
If we divide 8826 by 905, we get 9 and a remainder of 681.
The number 9 becomes the next digit in our result. 
Result so far: 8629.0
If we take 8145 away from 8826, we end up with 681.
Take the next digit (0) from the dividend and append it to 681, then repeat: 6810 / 905

Going ahead to step 8:
When dividing 6810 by 905, we get 7 with a remainder of 475.
Use 7 as the next digit of our solution. 
Result so far: 86297.0
If we take 6335 away from 6810, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 9:
905 can be fit into 4750 5 times, resulting in a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 86297.5
Deduct 4525 from 4750 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 10:
The number 905 fits into 2250 2 times, leaving a remainder of 440.
Record the quotient 2 as the next digit in the result. 
Result so far: 86297.52
The remainder is 440 after subtracting 1810 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
If we divide 4400 by 905, we get 4 and a remainder of 780.
Write down 4 as next digit of the result. 
Result so far: 86297.524
Deduct 3620 from 4400 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 12:
905 can be fit into 7800 8 times, resulting in a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 86297.5248
Subtract 7240 from 7800 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
905 goes into 5600 6 times with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 86297.52486
Subtracting 5430 from 5600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
If we divide 1700 by 905, we get 1 and a remainder of 795.
Record the quotient 1 as the next digit in the result. 
Result so far: 86297.524861
Subtracting 905 from 1700 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Going ahead to step 15:
If we divide 7950 by 905, we get 8 and a remainder of 710.
Use 8 as the next digit of our solution. 
Result so far: 86297.5248618
If we subtract 7240 from 7950, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 16:
If we divide 7100 by 905, we get 7 and a remainder of 765.
Record the quotient 7 as the next digit in the result. 
Result so far: 86297.52486187
Subtract 6335 from 7100 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

The final outcome is 86297.52486187, with a leftover of 7.65e-07.
