78944028 ÷ 902 
We want to figure out the number of times 78944028 can be divided by 902.

Going ahead to step 1:
The number 902 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 902

Going ahead to step 2:
The number 902 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 902

On to step 3:
If we divide 789 by 902, we get 0 and a remainder of 789.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 789 to get 789.
Bring next digit (4) of the dividend behind the 789 and repeat the process: 7894 / 902

Let's proceed to step 4:
902 can be fit into 7894 8 times, resulting in a remainder of 678.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7216 from 7894 leaves us with 678.
Include the next digit (4) from the dividend after 678, then repeat: 6784 / 902

Advancing to step 5:
The number 902 fits into 6784 7 times, leaving a remainder of 470.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 6314 from 6784 leaves us with 470.
Bring next digit (0) of the dividend behind the 470 and repeat the process: 4700 / 902

Let's proceed to step 6:
If we divide 4700 by 902, we get 5 and a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 875.0
Subtract 4510 from 4700 to get 190.
Append the next digit (2) from the dividend to 190 and continue with: 1902 / 902

Step 7:
1902 divided by 902 is 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 8752.0
If we subtract 1804 from 1902, we get 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 902

On to step 8:
When dividing 988 by 902, we get 1 with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 87521.0
Subtracting 902 from 988 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
902 goes into 860 0 times with a remainder of 860.
The number 0 becomes the next digit in our result. 
Result so far: 87521.0
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

On to step 10:
902 goes into 8600 9 times with a remainder of 482.
Record the quotient 9 as the next digit in the result. 
Result so far: 87521.09
The remainder is 482 after subtracting 8118 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 11:
The number 902 fits into 4820 5 times, leaving a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 87521.095
The remainder is 310 after subtracting 4510 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 12:
902 goes into 3100 3 times with a remainder of 394.
Write down 3 as next digit of the result. 
Result so far: 87521.0953
Deduct 2706 from 3100 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 13:
The number 902 fits into 3940 4 times, leaving a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 87521.09534
Subtracting 3608 from 3940 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 14:
902 can be fit into 3320 3 times, resulting in a remainder of 614.
The next digit of our result is 3. 
Result so far: 87521.095343
Subtract 2706 from 3320 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 15:
6140 divided by 902 is 6 with a remainder of 728.
Use 6 as the next digit of our solution. 
Result so far: 87521.0953436
Deduct 5412 from 6140 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 16:
If we divide 7280 by 902, we get 8 and a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 87521.09534368
Subtract 7216 from 7280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 87521.09534368, with a leftover of 6.4e-08.
