Let's divide 78448997 by 902
We want to divide 78448997 by 902.

Step 1:
7 divided by 902 is 0 with 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 902

On to step 2:
When dividing 78 by 902, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 902

Let's proceed to step 3:
If we divide 784 by 902, we get 0 and a remainder of 784.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 784 after subtracting 0 from 784.
Fetch the next digit (4) from the dividend, attach it to 784 and continue: 7844 / 902

Let's proceed to step 4:
When dividing 7844 by 902, we get 8 with a remainder of 628.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 628 after subtracting 7216 from 7844.
Take the next digit (8) from the dividend and append it to 628, then repeat: 6288 / 902

Going ahead to step 5:
902 goes into 6288 6 times with a remainder of 876.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 5412 from 6288 leaves us with 876.
Append the next digit (9) from the dividend to 876 and continue with: 8769 / 902

Advancing to step 6:
8769 divided by 902 is 9 with a remainder of 651.
Use 9 as the next digit of our solution. 
Result so far: 869.0
Deduct 8118 from 8769 and we're left with 651.
Bring next digit (9) of the dividend behind the 651 and repeat the process: 6519 / 902

Step 7:
902 goes into 6519 7 times with a remainder of 205.
Use 7 as the next digit of our solution. 
Result so far: 8697.0
Subtract 6314 from 6519 to get 205.
Take the next digit (7) from the dividend and append it to 205, then repeat: 2057 / 902

Moving on to step 8:
The number 902 fits into 2057 2 times, leaving a remainder of 253.
The number 2 becomes the next digit in our result. 
Result so far: 86972.0
Subtracting 1804 from 2057 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
902 can be fit into 2530 2 times, resulting in a remainder of 726.
Record the quotient 2 as the next digit in the result. 
Result so far: 86972.2
If we subtract 1804 from 2530, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 10:
When dividing 7260 by 902, we get 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 86972.28
If we take 7216 away from 7260, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
440 divided by 902 is 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 86972.28
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
902 can be fit into 4400 4 times, resulting in a remainder of 792.
The number 4 becomes the next digit in our result. 
Result so far: 86972.2804
Subtracting 3608 from 4400 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 13:
902 can be fit into 7920 8 times, resulting in a remainder of 704.
Use 8 as the next digit of our solution. 
Result so far: 86972.28048
The remainder is 704 after subtracting 7216 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 14:
902 can be fit into 7040 7 times, resulting in a remainder of 726.
The number 7 becomes the next digit in our result. 
Result so far: 86972.280487
If we subtract 6314 from 7040, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

On to step 15:
902 goes into 7260 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 86972.2804878
If we take 7216 away from 7260, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 16:
The number 902 fits into 440 0 times, leaving a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 86972.2804878
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 86972.2804878 with a remaining 4.4e-07.
