Let's divide 52286387 by 669
We want to divide 52286387 by 669.

On to step 1:
669 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 669

Let's proceed to step 2:
If we divide 52 by 669, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 669

Advancing to step 3:
If we divide 522 by 669, we get 0 and a remainder of 522.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 522 after subtracting 0 from 522.
Take the next digit (8) from the dividend and append it to 522, then repeat: 5228 / 669

Step 4:
669 goes into 5228 7 times with a remainder of 545.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4683 from 5228 to get 545.
Bring next digit (6) of the dividend behind the 545 and repeat the process: 5456 / 669

Let's proceed to step 5:
If we divide 5456 by 669, we get 8 and a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 5352 from 5456 to get 104.
Fetch the next digit (3) from the dividend, attach it to 104 and continue: 1043 / 669

Advancing to step 6:
669 goes into 1043 1 times with a remainder of 374.
The next digit of our result is 1. 
Result so far: 781.0
The remainder is 374 after subtracting 669 from 1043.
Include the next digit (8) from the dividend after 374, then repeat: 3748 / 669

Step 7:
669 can be fit into 3748 5 times, resulting in a remainder of 403.
The number 5 becomes the next digit in our result. 
Result so far: 7815.0
The remainder is 403 after subtracting 3345 from 3748.
Append the next digit (7) from the dividend to 403 and continue with: 4037 / 669

Step 8:
The number 669 fits into 4037 6 times, leaving a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 78156.0
Subtracting 4014 from 4037 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
669 goes into 230 0 times with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 78156.0
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
669 can be fit into 2300 3 times, resulting in a remainder of 293.
Write down 3 as next digit of the result. 
Result so far: 78156.03
If we take 2007 away from 2300, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 11:
669 goes into 2930 4 times with a remainder of 254.
The next digit of our result is 4. 
Result so far: 78156.034
Subtracting 2676 from 2930 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 12:
If we divide 2540 by 669, we get 3 and a remainder of 533.
Put 3 as the next digit of the answer. 
Result so far: 78156.0343
If we take 2007 away from 2540, we end up with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Step 13:
669 goes into 5330 7 times with a remainder of 647.
The next digit of our result is 7. 
Result so far: 78156.03437
Deduct 4683 from 5330 and we're left with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 14:
6470 divided by 669 is 9 with a remainder of 449.
Record the quotient 9 as the next digit in the result. 
Result so far: 78156.034379
Subtracting 6021 from 6470 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 15:
When dividing 4490 by 669, we get 6 with a remainder of 476.
Write down 6 as next digit of the result. 
Result so far: 78156.0343796
If we subtract 4014 from 4490, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 16:
The number 669 fits into 4760 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 78156.03437967
The remainder is 77 after subtracting 4683 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 78156.03437967, with a leftover of 7.7e-08.
