We look at the division of 59157509 by 399 
We're looking to find how many times 399 goes into 59157509.

Going ahead to step 1:
5 divided by 399 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 399

On to step 2:
If we divide 59 by 399, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 399

Moving on to step 3:
399 can be fit into 591 1 times, resulting in a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 399 from 591 to get 192.
Fetch the next digit (5) from the dividend, attach it to 192 and continue: 1925 / 399

Advancing to step 4:
If we divide 1925 by 399, we get 4 and a remainder of 329.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1596 from 1925 and we're left with 329.
Bring next digit (7) of the dividend behind the 329 and repeat the process: 3297 / 399

Going ahead to step 5:
If we divide 3297 by 399, we get 8 and a remainder of 105.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we take 3192 away from 3297, we end up with 105.
Bring next digit (5) of the dividend behind the 105 and repeat the process: 1055 / 399

Let's proceed to step 6:
399 goes into 1055 2 times with a remainder of 257.
The next digit of our result is 2. 
Result so far: 1482.0
Deduct 798 from 1055 and we're left with 257.
Append the next digit (0) from the dividend to 257 and continue with: 2570 / 399

Step 7:
When dividing 2570 by 399, we get 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 14826.0
The remainder is 176 after subtracting 2394 from 2570.
Take the next digit (9) from the dividend and append it to 176, then repeat: 1769 / 399

Let's proceed to step 8:
The number 399 fits into 1769 4 times, leaving a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 148264.0
If we subtract 1596 from 1769, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 9:
1730 divided by 399 is 4 with a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 148264.4
Subtract 1596 from 1730 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
399 goes into 1340 3 times with a remainder of 143.
Write down 3 as next digit of the result. 
Result so far: 148264.43
Subtracting 1197 from 1340 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 11:
1430 divided by 399 is 3 with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 148264.433
Subtract 1197 from 1430 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

In conclusion, the division gives 148264.433 with a balance of 0.0233.
