90873396 ÷ 78 
Our goal is to divide 90873396 by 78.

Advancing to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 78

Step 2:
If we divide 90 by 78, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 78 away from 90, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 78

Moving on to step 3:
When dividing 128 by 78, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 78 away from 128, we end up with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 78

Moving on to step 4:
When dividing 507 by 78, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 468 from 507, we get 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 78

Step 5:
When dividing 393 by 78, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1165.0
If we subtract 390 from 393, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 78

Going ahead to step 6:
The number 78 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 11650.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 78

Step 7:
If we divide 339 by 78, we get 4 and a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 116504.0
Subtract 312 from 339 to get 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 78

Moving on to step 8:
276 divided by 78 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1165043.0
If we subtract 234 from 276, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1165043.5
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 1165043.53
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1165043.538
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 78 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 1165043.5384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
78 goes into 480 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1165043.53846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
When dividing 120 by 78, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1165043.538461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 15:
78 goes into 420 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1165043.5384615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
If we divide 300 by 78, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 1165043.53846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 1165043.53846153 with a balance of 6.6e-08.
