We look at the division of 57919758 by 399 
Our goal is to divide 57919758 by 399.

Moving on to step 1:
5 divided by 399 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 399

Going ahead to step 2:
57 divided by 399 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 399

Step 3:
579 divided by 399 is 1 with a remainder of 180.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 399 from 579 to get 180.
Grab the next digit (1) from the dividend, add it to 180, then carry on: 1801 / 399

Going ahead to step 4:
399 can be fit into 1801 4 times, resulting in a remainder of 205.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1596 from 1801 and we're left with 205.
Append the next digit (9) from the dividend to 205 and continue with: 2059 / 399

Advancing to step 5:
The number 399 fits into 2059 5 times, leaving a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 1995 away from 2059, we end up with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 399

Step 6:
When dividing 647 by 399, we get 1 with a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1451.0
Subtract 399 from 647 to get 248.
Include the next digit (5) from the dividend after 248, then repeat: 2485 / 399

On to step 7:
2485 divided by 399 is 6 with a remainder of 91.
The next digit of our result is 6. 
Result so far: 14516.0
Deduct 2394 from 2485 and we're left with 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 399

Going ahead to step 8:
When dividing 918 by 399, we get 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 145162.0
If we subtract 798 from 918, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
When dividing 1200 by 399, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 145162.3
Subtract 1197 from 1200 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
399 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 145162.3
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
399 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 145162.3
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 145162.3 with a balance of 0.03.
