Let's divide 77648189 by 869
We're looking to find how many times 869 goes into 77648189.

Advancing to step 1:
If we divide 7 by 869, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 869

Let's proceed to step 2:
869 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 869

Step 3:
869 can be fit into 776 0 times, resulting in a remainder of 776.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 776 leaves us with 776.
Include the next digit (4) from the dividend after 776, then repeat: 7764 / 869

Advancing to step 4:
The number 869 fits into 7764 8 times, leaving a remainder of 812.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6952 away from 7764, we end up with 812.
Append the next digit (8) from the dividend to 812 and continue with: 8128 / 869

On to step 5:
The number 869 fits into 8128 9 times, leaving a remainder of 307.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 307 after subtracting 7821 from 8128.
Include the next digit (1) from the dividend after 307, then repeat: 3071 / 869

Going ahead to step 6:
When dividing 3071 by 869, we get 3 with a remainder of 464.
The number 3 becomes the next digit in our result. 
Result so far: 893.0
If we subtract 2607 from 3071, we get 464.
Fetch the next digit (8) from the dividend, attach it to 464 and continue: 4648 / 869

On to step 7:
When dividing 4648 by 869, we get 5 with a remainder of 303.
Record the quotient 5 as the next digit in the result. 
Result so far: 8935.0
Subtracting 4345 from 4648 leaves us with 303.
Fetch the next digit (9) from the dividend, attach it to 303 and continue: 3039 / 869

Moving on to step 8:
If we divide 3039 by 869, we get 3 and a remainder of 432.
Use 3 as the next digit of our solution. 
Result so far: 89353.0
Subtract 2607 from 3039 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 9:
If we divide 4320 by 869, we get 4 and a remainder of 844.
The number 4 becomes the next digit in our result. 
Result so far: 89353.4
Subtracting 3476 from 4320 leaves us with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 10:
When dividing 8440 by 869, we get 9 with a remainder of 619.
Write down 9 as next digit of the result. 
Result so far: 89353.49
Subtract 7821 from 8440 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 11:
6190 divided by 869 is 7 with a remainder of 107.
The next digit of our result is 7. 
Result so far: 89353.497
Deduct 6083 from 6190 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 12:
1070 divided by 869 is 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 89353.4971
Subtracting 869 from 1070 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 13:
869 can be fit into 2010 2 times, resulting in a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 89353.49712
Subtracting 1738 from 2010 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 14:
869 can be fit into 2720 3 times, resulting in a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 89353.497123
If we subtract 2607 from 2720, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 15:
If we divide 1130 by 869, we get 1 and a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 89353.4971231
If we subtract 869 from 1130, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 16:
869 can be fit into 2610 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 89353.49712313
The remainder is 3 after subtracting 2607 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 89353.49712313 with a remaining 3e-09.
