Let's divide 221146 by 78
We want to divide 221146 by 78.

On to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 78

Advancing to step 2:
If we divide 22 by 78, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 78

On to step 3:
If we divide 221 by 78, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 156 from 221 to get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 78

Step 4:
The number 78 fits into 651 8 times, leaving a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 624 away from 651, we end up with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 78

Advancing to step 5:
78 can be fit into 274 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 283.0
Subtracting 234 from 274 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 78

Let's proceed to step 6:
The number 78 fits into 406 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 2835.0
Subtract 390 from 406 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2835.2
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2835.2
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 78, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2835.205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 2835.2051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2835.20512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
If we divide 640 by 78, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2835.205128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2835.2051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2835.2051282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 2835.2051282 with a remaining 4e-08.
