58986368 ÷ 399 
We're looking to find how many times 399 goes into 58986368.

Let's proceed to step 1:
5 divided by 399 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 399

Let's proceed to step 2:
399 can be fit into 58 0 times, resulting in a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 399

Let's proceed to step 3:
399 goes into 589 1 times with a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 190 after subtracting 399 from 589.
Bring next digit (8) of the dividend behind the 190 and repeat the process: 1908 / 399

Step 4:
The number 399 fits into 1908 4 times, leaving a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 312 after subtracting 1596 from 1908.
Append the next digit (6) from the dividend to 312 and continue with: 3126 / 399

Step 5:
The number 399 fits into 3126 7 times, leaving a remainder of 333.
Put 7 as the next digit of the answer. 
Result so far: 147.0
If we subtract 2793 from 3126, we get 333.
Bring next digit (3) of the dividend behind the 333 and repeat the process: 3333 / 399

On to step 6:
399 can be fit into 3333 8 times, resulting in a remainder of 141.
Record the quotient 8 as the next digit in the result. 
Result so far: 1478.0
If we subtract 3192 from 3333, we get 141.
Fetch the next digit (6) from the dividend, attach it to 141 and continue: 1416 / 399

Let's proceed to step 7:
1416 divided by 399 is 3 with a remainder of 219.
Put 3 as the next digit of the answer. 
Result so far: 14783.0
Subtracting 1197 from 1416 leaves us with 219.
Bring next digit (8) of the dividend behind the 219 and repeat the process: 2198 / 399

Moving on to step 8:
399 goes into 2198 5 times with a remainder of 203.
Write down 5 as next digit of the result. 
Result so far: 147835.0
If we take 1995 away from 2198, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
399 can be fit into 2030 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 147835.5
The remainder is 35 after subtracting 1995 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
350 divided by 399 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 147835.5
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
399 can be fit into 3500 8 times, resulting in a remainder of 308.
Put 8 as the next digit of the answer. 
Result so far: 147835.508
If we take 3192 away from 3500, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 12:
3080 divided by 399 is 7 with a remainder of 287.
Record the quotient 7 as the next digit in the result. 
Result so far: 147835.5087
The remainder is 287 after subtracting 2793 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 13:
The number 399 fits into 2870 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 147835.50877
Subtract 2793 from 2870 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final result is 147835.50877 with a remainder of 7.7e-05.
