If we divide 4 by 869, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 869

Moving on to step 2:
If we divide 45 by 869, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 869

Going ahead to step 3:
869 goes into 454 0 times with a remainder of 454.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 454 and we're left with 454.
Grab the next digit (0) from the dividend, add it to 454, then carry on: 4540 / 869

Going ahead to step 4:
4540 divided by 869 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4345 from 4540 and we're left with 195.
Take the next digit (3) from the dividend and append it to 195, then repeat: 1953 / 869

On to step 5:
869 can be fit into 1953 2 times, resulting in a remainder of 215.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 215 after subtracting 1738 from 1953.
Append the next digit (9) from the dividend to 215 and continue with: 2159 / 869

On to step 6:
If we divide 2159 by 869, we get 2 and a remainder of 421.
The next digit of our result is 2. 
Result so far: 522.0
Subtracting 1738 from 2159 leaves us with 421.
Append the next digit (4) from the dividend to 421 and continue with: 4214 / 869

Advancing to step 7:
869 goes into 4214 4 times with a remainder of 738.
The number 4 becomes the next digit in our result. 
Result so far: 5224.0
If we take 3476 away from 4214, we end up with 738.
Fetch the next digit (5) from the dividend, attach it to 738 and continue: 7385 / 869

Step 8:
When dividing 7385 by 869, we get 8 with a remainder of 433.
Record the quotient 8 as the next digit in the result. 
Result so far: 52248.0
Subtracting 6952 from 7385 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
The number 869 fits into 4330 4 times, leaving a remainder of 854.
Use 4 as the next digit of our solution. 
Result so far: 52248.4
The remainder is 854 after subtracting 3476 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 10:
When dividing 8540 by 869, we get 9 with a remainder of 719.
The number 9 becomes the next digit in our result. 
Result so far: 52248.49
The remainder is 719 after subtracting 7821 from 8540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Advancing to step 11:
869 can be fit into 7190 8 times, resulting in a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 52248.498
If we subtract 6952 from 7190, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 12:
When dividing 2380 by 869, we get 2 with a remainder of 642.
The next digit of our result is 2. 
Result so far: 52248.4982
If we take 1738 away from 2380, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Step 13:
869 goes into 6420 7 times with a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 52248.49827
Deduct 6083 from 6420 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 14:
3370 divided by 869 is 3 with a remainder of 763.
Put 3 as the next digit of the answer. 
Result so far: 52248.498273
Subtracting 2607 from 3370 leaves us with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Advancing to step 15:
When dividing 7630 by 869, we get 8 with a remainder of 678.
Put 8 as the next digit of the answer. 
Result so far: 52248.4982738
The remainder is 678 after subtracting 6952 from 7630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 16:
When dividing 6780 by 869, we get 7 with a remainder of 697.
The next digit of our result is 7. 
Result so far: 52248.49827387
If we subtract 6083 from 6780, we get 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Our division results in 52248.49827387 with a remaining 6.97e-07.
