83816598 divided by 78 
We want to figure out the number of times 83816598 can be divided by 78.

Advancing to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 78

Advancing to step 2:
If we divide 83 by 78, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 83 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 78

On to step 3:
If we divide 58 by 78, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 58 after subtracting 0 from 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 78

Going ahead to step 4:
The number 78 fits into 581 7 times, leaving a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 546 from 581, we get 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 78

Step 5:
When dividing 356 by 78, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 1074.0
Deduct 312 from 356 and we're left with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 78

Moving on to step 6:
The number 78 fits into 445 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 10745.0
Subtract 390 from 445 to get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 78

Let's proceed to step 7:
If we divide 559 by 78, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 107457.0
If we subtract 546 from 559, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 78

Advancing to step 8:
78 can be fit into 138 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1074571.0
The remainder is 60 after subtracting 78 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1074571.7
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1074571.76
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
When dividing 720 by 78, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 1074571.769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1074571.7692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1074571.76923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
60 divided by 78 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1074571.76923
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 1074571.7692307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 16:
The number 78 fits into 540 6 times, leaving a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 1074571.76923076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 1074571.76923076 and a remainder of 7.2e-08.
