We look at the division of 63826389 by 166 
We want to figure out the number of times 63826389 can be divided by 166.

Moving on to step 1:
If we divide 6 by 166, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 166

Step 2:
166 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 166

Going ahead to step 3:
166 can be fit into 638 3 times, resulting in a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 140 after subtracting 498 from 638.
Bring next digit (2) of the dividend behind the 140 and repeat the process: 1402 / 166

Advancing to step 4:
When dividing 1402 by 166, we get 8 with a remainder of 74.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 1328 from 1402 and we're left with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 166

Advancing to step 5:
When dividing 746 by 166, we get 4 with a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 384.0
If we subtract 664 from 746, we get 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 166

Step 6:
If we divide 823 by 166, we get 4 and a remainder of 159.
Put 4 as the next digit of the answer. 
Result so far: 3844.0
The remainder is 159 after subtracting 664 from 823.
Grab the next digit (8) from the dividend, add it to 159, then carry on: 1598 / 166

On to step 7:
The number 166 fits into 1598 9 times, leaving a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 38449.0
The remainder is 104 after subtracting 1494 from 1598.
Take the next digit (9) from the dividend and append it to 104, then repeat: 1049 / 166

Step 8:
If we divide 1049 by 166, we get 6 and a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 384496.0
Subtract 996 from 1049 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
166 can be fit into 530 3 times, resulting in a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 384496.3
The remainder is 32 after subtracting 498 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 166 fits into 320 1 times, leaving a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 384496.31
If we take 166 away from 320, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
The number 166 fits into 1540 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 384496.319
Deduct 1494 from 1540 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
When dividing 460 by 166, we get 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 384496.3192
If we take 332 away from 460, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
When dividing 1280 by 166, we get 7 with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 384496.31927
The remainder is 118 after subtracting 1162 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 14:
The number 166 fits into 1180 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 384496.319277
If we subtract 1162 from 1180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 384496.319277, with a leftover of 1.8e-06.
