Let's divide 12120112 by 945
We want to divide 12120112 by 945.

On to step 1:
1 divided by 945 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 945

Advancing to step 2:
If we divide 12 by 945, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 945

Let's proceed to step 3:
945 can be fit into 121 0 times, resulting in a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 121, we end up with 121.
Include the next digit (2) from the dividend after 121, then repeat: 1212 / 945

Let's proceed to step 4:
When dividing 1212 by 945, we get 1 with a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 945 away from 1212, we end up with 267.
Fetch the next digit (0) from the dividend, attach it to 267 and continue: 2670 / 945

On to step 5:
945 goes into 2670 2 times with a remainder of 780.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1890 from 2670 to get 780.
Bring next digit (1) of the dividend behind the 780 and repeat the process: 7801 / 945

Let's proceed to step 6:
945 goes into 7801 8 times with a remainder of 241.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 7560 from 7801 and we're left with 241.
Append the next digit (1) from the dividend to 241 and continue with: 2411 / 945

Let's proceed to step 7:
945 goes into 2411 2 times with a remainder of 521.
The next digit of our result is 2. 
Result so far: 1282.0
The remainder is 521 after subtracting 1890 from 2411.
Take the next digit (2) from the dividend and append it to 521, then repeat: 5212 / 945

Step 8:
5212 divided by 945 is 5 with a remainder of 487.
Put 5 as the next digit of the answer. 
Result so far: 12825.0
If we subtract 4725 from 5212, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 9:
The number 945 fits into 4870 5 times, leaving a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 12825.5
If we take 4725 away from 4870, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 10:
945 can be fit into 1450 1 times, resulting in a remainder of 505.
The next digit of our result is 1. 
Result so far: 12825.51
If we take 945 away from 1450, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 11:
When dividing 5050 by 945, we get 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 12825.515
If we subtract 4725 from 5050, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 12:
945 can be fit into 3250 3 times, resulting in a remainder of 415.
Use 3 as the next digit of our solution. 
Result so far: 12825.5153
If we subtract 2835 from 3250, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 13:
945 goes into 4150 4 times with a remainder of 370.
Record the quotient 4 as the next digit in the result. 
Result so far: 12825.51534
If we take 3780 away from 4150, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
When dividing 3700 by 945, we get 3 with a remainder of 865.
The number 3 becomes the next digit in our result. 
Result so far: 12825.515343
Deduct 2835 from 3700 and we're left with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Step 15:
945 goes into 8650 9 times with a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 12825.5153439
Subtract 8505 from 8650 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 16:
When dividing 1450 by 945, we get 1 with a remainder of 505.
Write down 1 as next digit of the result. 
Result so far: 12825.51534391
Subtracting 945 from 1450 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Our division results in 12825.51534391 with a remaining 5.05e-07.
