We're dividing 39806443 by 455 
Our goal is to divide 39806443 by 455.

Going ahead to step 1:
455 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 455

Let's proceed to step 2:
39 divided by 455 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 455

Advancing to step 3:
455 can be fit into 398 0 times, resulting in a remainder of 398.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 398, we end up with 398.
Fetch the next digit (0) from the dividend, attach it to 398 and continue: 3980 / 455

On to step 4:
455 can be fit into 3980 8 times, resulting in a remainder of 340.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 3640 from 3980 to get 340.
Append the next digit (6) from the dividend to 340 and continue with: 3406 / 455

Moving on to step 5:
The number 455 fits into 3406 7 times, leaving a remainder of 221.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtracting 3185 from 3406 leaves us with 221.
Include the next digit (4) from the dividend after 221, then repeat: 2214 / 455

Going ahead to step 6:
The number 455 fits into 2214 4 times, leaving a remainder of 394.
Use 4 as the next digit of our solution. 
Result so far: 874.0
Deduct 1820 from 2214 and we're left with 394.
Grab the next digit (4) from the dividend, add it to 394, then carry on: 3944 / 455

Let's proceed to step 7:
455 goes into 3944 8 times with a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 8748.0
Deduct 3640 from 3944 and we're left with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 455

Advancing to step 8:
455 can be fit into 3043 6 times, resulting in a remainder of 313.
Write down 6 as next digit of the result. 
Result so far: 87486.0
If we subtract 2730 from 3043, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
When dividing 3130 by 455, we get 6 with a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 87486.6
If we take 2730 away from 3130, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
When dividing 4000 by 455, we get 8 with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 87486.68
Subtracting 3640 from 4000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
3600 divided by 455 is 7 with a remainder of 415.
Record the quotient 7 as the next digit in the result. 
Result so far: 87486.687
If we take 3185 away from 3600, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 12:
The number 455 fits into 4150 9 times, leaving a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 87486.6879
Subtracting 4095 from 4150 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
If we divide 550 by 455, we get 1 and a remainder of 95.
The next digit of our result is 1. 
Result so far: 87486.68791
If we take 455 away from 550, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 14:
The number 455 fits into 950 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 87486.687912
Subtract 910 from 950 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
The number 455 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 87486.687912
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
If we divide 4000 by 455, we get 8 and a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 87486.68791208
If we subtract 3640 from 4000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 87486.68791208 with a balance of 3.6e-07.
