39244369 ÷ 869 
Our goal is to divide 39244369 by 869.

Going ahead to step 1:
869 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 869

Moving on to step 2:
869 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 869

Moving on to step 3:
392 divided by 869 is 0 with a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Grab the next digit (4) from the dividend, add it to 392, then carry on: 3924 / 869

Advancing to step 4:
The number 869 fits into 3924 4 times, leaving a remainder of 448.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 448 after subtracting 3476 from 3924.
Bring next digit (4) of the dividend behind the 448 and repeat the process: 4484 / 869

Step 5:
The number 869 fits into 4484 5 times, leaving a remainder of 139.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 4345 from 4484 leaves us with 139.
Fetch the next digit (3) from the dividend, attach it to 139 and continue: 1393 / 869

Advancing to step 6:
The number 869 fits into 1393 1 times, leaving a remainder of 524.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
If we subtract 869 from 1393, we get 524.
Take the next digit (6) from the dividend and append it to 524, then repeat: 5246 / 869

Let's proceed to step 7:
5246 divided by 869 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 4516.0
Subtract 5214 from 5246 to get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 869

Going ahead to step 8:
329 divided by 869 is 0 with a remainder of 329.
Put 0 as the next digit of the answer. 
Result so far: 45160.0
Subtracting 0 from 329 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
When dividing 3290 by 869, we get 3 with a remainder of 683.
Write down 3 as next digit of the result. 
Result so far: 45160.3
If we subtract 2607 from 3290, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Moving on to step 10:
If we divide 6830 by 869, we get 7 and a remainder of 747.
Write down 7 as next digit of the result. 
Result so far: 45160.37
Subtracting 6083 from 6830 leaves us with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Step 11:
When dividing 7470 by 869, we get 8 with a remainder of 518.
The number 8 becomes the next digit in our result. 
Result so far: 45160.378
If we subtract 6952 from 7470, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 12:
869 goes into 5180 5 times with a remainder of 835.
Use 5 as the next digit of our solution. 
Result so far: 45160.3785
The remainder is 835 after subtracting 4345 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Step 13:
The number 869 fits into 8350 9 times, leaving a remainder of 529.
Put 9 as the next digit of the answer. 
Result so far: 45160.37859
Subtracting 7821 from 8350 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Moving on to step 14:
869 goes into 5290 6 times with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 45160.378596
If we take 5214 away from 5290, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
869 can be fit into 760 0 times, resulting in a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 45160.378596
Subtracting 0 from 760 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 16:
When dividing 7600 by 869, we get 8 with a remainder of 648.
Record the quotient 8 as the next digit in the result. 
Result so far: 45160.37859608
If we take 6952 away from 7600, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

The final result is 45160.37859608 with a remainder of 6.48e-07.
