Let's divide 12253277 by 577
We want to figure out the number of times 12253277 can be divided by 577.

Advancing to step 1:
577 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 577

Step 2:
12 divided by 577 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 577

Step 3:
When dividing 122 by 577, we get 0 with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 577

Advancing to step 4:
577 goes into 1225 2 times with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1154 from 1225 leaves us with 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 577

Advancing to step 5:
577 goes into 713 1 times with a remainder of 136.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 136 after subtracting 577 from 713.
Include the next digit (2) from the dividend after 136, then repeat: 1362 / 577

Moving on to step 6:
If we divide 1362 by 577, we get 2 and a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtract 1154 from 1362 to get 208.
Bring next digit (7) of the dividend behind the 208 and repeat the process: 2087 / 577

Let's proceed to step 7:
577 goes into 2087 3 times with a remainder of 356.
Put 3 as the next digit of the answer. 
Result so far: 2123.0
If we subtract 1731 from 2087, we get 356.
Bring next digit (7) of the dividend behind the 356 and repeat the process: 3567 / 577

Moving on to step 8:
3567 divided by 577 is 6 with a remainder of 105.
Write down 6 as next digit of the result. 
Result so far: 21236.0
The remainder is 105 after subtracting 3462 from 3567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
577 can be fit into 1050 1 times, resulting in a remainder of 473.
The next digit of our result is 1. 
Result so far: 21236.1
If we subtract 577 from 1050, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 10:
577 goes into 4730 8 times with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 21236.18
The remainder is 114 after subtracting 4616 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 11:
1140 divided by 577 is 1 with a remainder of 563.
Use 1 as the next digit of our solution. 
Result so far: 21236.181
If we take 577 away from 1140, we end up with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Advancing to step 12:
577 can be fit into 5630 9 times, resulting in a remainder of 437.
The next digit of our result is 9. 
Result so far: 21236.1819
Deduct 5193 from 5630 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 13:
577 can be fit into 4370 7 times, resulting in a remainder of 331.
Record the quotient 7 as the next digit in the result. 
Result so far: 21236.18197
If we subtract 4039 from 4370, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 14:
The number 577 fits into 3310 5 times, leaving a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 21236.181975
If we subtract 2885 from 3310, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 15:
When dividing 4250 by 577, we get 7 with a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 21236.1819757
The remainder is 211 after subtracting 4039 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 16:
577 can be fit into 2110 3 times, resulting in a remainder of 379.
Put 3 as the next digit of the answer. 
Result so far: 21236.18197573
Subtract 1731 from 2110 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Our division results in 21236.18197573 with a remaining 3.79e-07.
