Let's divide 48589294 by 399
Our goal is to divide 48589294 by 399.

Advancing to step 1:
When dividing 4 by 399, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 399

Let's proceed to step 2:
399 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 399

On to step 3:
399 goes into 485 1 times with a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 399 from 485 leaves us with 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 399

Advancing to step 4:
399 can be fit into 868 2 times, resulting in a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 798 away from 868, we end up with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 399

Advancing to step 5:
399 goes into 709 1 times with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 399 away from 709, we end up with 310.
Bring next digit (2) of the dividend behind the 310 and repeat the process: 3102 / 399

Step 6:
When dividing 3102 by 399, we get 7 with a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
Subtracting 2793 from 3102 leaves us with 309.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 399

Going ahead to step 7:
When dividing 3099 by 399, we get 7 with a remainder of 306.
Put 7 as the next digit of the answer. 
Result so far: 12177.0
If we take 2793 away from 3099, we end up with 306.
Append the next digit (4) from the dividend to 306 and continue with: 3064 / 399

Step 8:
If we divide 3064 by 399, we get 7 and a remainder of 271.
Use 7 as the next digit of our solution. 
Result so far: 121777.0
If we subtract 2793 from 3064, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 9:
399 can be fit into 2710 6 times, resulting in a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 121777.6
If we take 2394 away from 2710, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 10:
If we divide 3160 by 399, we get 7 and a remainder of 367.
The number 7 becomes the next digit in our result. 
Result so far: 121777.67
The remainder is 367 after subtracting 2793 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 11:
When dividing 3670 by 399, we get 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 121777.679
If we take 3591 away from 3670, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 12:
399 can be fit into 790 1 times, resulting in a remainder of 391.
Use 1 as the next digit of our solution. 
Result so far: 121777.6791
Subtracting 399 from 790 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 13:
399 goes into 3910 9 times with a remainder of 319.
The number 9 becomes the next digit in our result. 
Result so far: 121777.67919
The remainder is 319 after subtracting 3591 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 14:
399 can be fit into 3190 7 times, resulting in a remainder of 397.
Write down 7 as next digit of the result. 
Result so far: 121777.679197
Deduct 2793 from 3190 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 15:
399 can be fit into 3970 9 times, resulting in a remainder of 379.
Use 9 as the next digit of our solution. 
Result so far: 121777.6791979
If we subtract 3591 from 3970, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 16:
399 can be fit into 3790 9 times, resulting in a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 121777.67919799
If we subtract 3591 from 3790, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Our division results in 121777.67919799 with a remaining 1.99e-07.
