Let's divide 58156544 by 399
We want to figure out the number of times 58156544 can be divided by 399.

Step 1:
399 goes into 5 0 times 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.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 399

Let's proceed to step 2:
The number 399 fits into 58 0 times, leaving a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 399

On to step 3:
The number 399 fits into 581 1 times, leaving a remainder of 182.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 399 from 581, we get 182.
Fetch the next digit (5) from the dividend, attach it to 182 and continue: 1825 / 399

Advancing to step 4:
399 goes into 1825 4 times with a remainder of 229.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 1596 from 1825 leaves us with 229.
Take the next digit (6) from the dividend and append it to 229, then repeat: 2296 / 399

Advancing to step 5:
399 goes into 2296 5 times with a remainder of 301.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtract 1995 from 2296 to get 301.
Take the next digit (5) from the dividend and append it to 301, then repeat: 3015 / 399

Going ahead to step 6:
399 goes into 3015 7 times with a remainder of 222.
Use 7 as the next digit of our solution. 
Result so far: 1457.0
If we subtract 2793 from 3015, we get 222.
Grab the next digit (4) from the dividend, add it to 222, then carry on: 2224 / 399

On to step 7:
The number 399 fits into 2224 5 times, leaving a remainder of 229.
Use 5 as the next digit of our solution. 
Result so far: 14575.0
Subtracting 1995 from 2224 leaves us with 229.
Grab the next digit (4) from the dividend, add it to 229, then carry on: 2294 / 399

Moving on to step 8:
If we divide 2294 by 399, we get 5 and a remainder of 299.
Write down 5 as next digit of the result. 
Result so far: 145755.0
Subtracting 1995 from 2294 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
The number 399 fits into 2990 7 times, leaving a remainder of 197.
The next digit of our result is 7. 
Result so far: 145755.7
Subtract 2793 from 2990 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
399 can be fit into 1970 4 times, resulting in a remainder of 374.
Put 4 as the next digit of the answer. 
Result so far: 145755.74
Subtract 1596 from 1970 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 11:
If we divide 3740 by 399, we get 9 and a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 145755.749
The remainder is 149 after subtracting 3591 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 12:
399 goes into 1490 3 times with a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 145755.7493
Subtract 1197 from 1490 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 13:
399 goes into 2930 7 times with a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 145755.74937
Subtract 2793 from 2930 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 14:
If we divide 1370 by 399, we get 3 and a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 145755.749373
The remainder is 173 after subtracting 1197 from 1370.
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 15:
399 goes into 1730 4 times with a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 145755.7493734
Subtracting 1596 from 1730 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 16:
When dividing 1340 by 399, we get 3 with a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 145755.74937343
The remainder is 143 after subtracting 1197 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

After the division, we end up with 145755.74937343 and a remainder of 1.43e-07.
