7712791 ÷ 345 
Our goal is to divide 7712791 by 345.

Step 1:
345 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 345

Step 2:
When dividing 77 by 345, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 345

Moving on to step 3:
345 can be fit into 771 2 times, resulting in a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 690 from 771, we get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 345

On to step 4:
When dividing 812 by 345, we get 2 with a remainder of 122.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 690 from 812, we get 122.
Grab the next digit (7) from the dividend, add it to 122, then carry on: 1227 / 345

Advancing to step 5:
345 goes into 1227 3 times with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Subtract 1035 from 1227 to get 192.
Fetch the next digit (9) from the dividend, attach it to 192 and continue: 1929 / 345

Advancing to step 6:
1929 divided by 345 is 5 with a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 2235.0
Subtracting 1725 from 1929 leaves us with 204.
Bring next digit (1) of the dividend behind the 204 and repeat the process: 2041 / 345

On to step 7:
When dividing 2041 by 345, we get 5 with a remainder of 316.
The number 5 becomes the next digit in our result. 
Result so far: 22355.0
Deduct 1725 from 2041 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 8:
If we divide 3160 by 345, we get 9 and a remainder of 55.
The next digit of our result is 9. 
Result so far: 22355.9
Subtract 3105 from 3160 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
550 divided by 345 is 1 with a remainder of 205.
Use 1 as the next digit of our solution. 
Result so far: 22355.91
If we take 345 away from 550, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 10:
The number 345 fits into 2050 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 22355.915
Subtract 1725 from 2050 to 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.

Step 11:
The number 345 fits into 3250 9 times, leaving a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 22355.9159
Subtracting 3105 from 3250 leaves us 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.

Let's proceed to step 12:
1450 divided by 345 is 4 with a remainder of 70.
The next digit of our result is 4. 
Result so far: 22355.91594
Subtracting 1380 from 1450 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
The number 345 fits into 700 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 22355.915942
Subtracting 690 from 700 leaves us 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.

Moving on to step 14:
345 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 22355.915942
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
When dividing 1000 by 345, we get 2 with a remainder of 310.
Write down 2 as next digit of the result. 
Result so far: 22355.91594202
The remainder is 310 after subtracting 690 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Our division results in 22355.91594202 with a remaining 3.1e-07.
