901700 ÷ 78 
We want to divide 901700 by 78.

On to step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 78

Advancing to step 2:
90 divided by 78 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 78 away from 90, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 78

Step 3:
The number 78 fits into 121 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 78 away from 121, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 78

Advancing to step 4:
78 can be fit into 437 5 times, resulting in a remainder of 47.
The next digit of our result is 5. 
Result so far: 115.0
Subtracting 390 from 437 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 78

On to step 5:
78 goes into 470 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1156.0
If we take 468 away from 470, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 78

On to step 6:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11560.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 78 fits into 200 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 11560.2
If we subtract 156 from 200, we get 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 8:
440 divided by 78 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11560.25
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
500 divided by 78 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11560.256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
78 can be fit into 320 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 11560.2564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11560.25641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11560.25641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11560.2564102
Deduct 156 from 200 and we're left 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 14:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 11560.25641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 11560.25641025 with a remaining 5e-08.
