We're dividing 721625 by 78 
Let's see how many times 78 fits into 721625.

Advancing to step 1:
7 divided by 78 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 78

On to step 2:
78 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 78

On to step 3:
If we divide 721 by 78, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 702 away from 721, we end up with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 78

Advancing to step 4:
When dividing 196 by 78, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Deduct 156 from 196 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 78

Going ahead to step 5:
78 can be fit into 402 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 925.0
If we take 390 away from 402, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 78

Advancing to step 6:
If we divide 125 by 78, we get 1 and a remainder of 47.
The next digit of our result is 1. 
Result so far: 9251.0
The remainder is 47 after subtracting 78 from 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
If we divide 470 by 78, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 9251.6
Deduct 468 from 470 and we're left 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.

On to step 8:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9251.6
If we take 0 away from 20, we end up 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.

Let's proceed to step 9:
78 goes into 200 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 9251.602
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.

Let's proceed to step 10:
The number 78 fits into 440 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9251.6025
Subtracting 390 from 440 leaves us 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.

Let's proceed to step 11:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 9251.60256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9251.602564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 78 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 9251.6025641
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.

Let's proceed to step 14:
78 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 9251.6025641
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.

After the division, we end up with 9251.6025641 and a remainder of 2e-08.
