We're dividing 12959137 by 223 
Our goal is to divide 12959137 by 223.

Let's proceed to step 1:
223 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 223

Moving on to step 2:
The number 223 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 223

Let's proceed to step 3:
If we divide 129 by 223, we get 0 and a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Grab the next digit (5) from the dividend, add it to 129, then carry on: 1295 / 223

On to step 4:
If we divide 1295 by 223, we get 5 and a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 180 after subtracting 1115 from 1295.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 223

Advancing to step 5:
223 goes into 1809 8 times with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 1784 from 1809 to get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 223

On to step 6:
251 divided by 223 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 581.0
Subtracting 223 from 251 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 223

Let's proceed to step 7:
223 goes into 283 1 times with a remainder of 60.
The next digit of our result is 1. 
Result so far: 5811.0
Subtracting 223 from 283 leaves us with 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 223

Let's proceed to step 8:
223 can be fit into 607 2 times, resulting in a remainder of 161.
Use 2 as the next digit of our solution. 
Result so far: 58112.0
If we take 446 away from 607, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 9:
When dividing 1610 by 223, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 58112.7
Deduct 1561 from 1610 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
223 can be fit into 490 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 58112.72
If we take 446 away from 490, we end up 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.

Going ahead to step 11:
The number 223 fits into 440 1 times, leaving a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 58112.721
If we take 223 away from 440, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 12:
When dividing 2170 by 223, we get 9 with a remainder of 163.
Put 9 as the next digit of the answer. 
Result so far: 58112.7219
If we take 2007 away from 2170, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 13:
The number 223 fits into 1630 7 times, leaving a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 58112.72197
If we take 1561 away from 1630, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
If we divide 690 by 223, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 58112.721973
The remainder is 21 after subtracting 669 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 15:
The number 223 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 58112.721973
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 16:
223 goes into 2100 9 times with a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 58112.72197309
If we take 2007 away from 2100, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final outcome is 58112.72197309, with a leftover of 9.3e-08.
