39851590 ÷ 359 
We want to figure out the number of times 39851590 can be divided by 359.

Moving on to step 1:
The number 359 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 359

On to step 2:
When dividing 39 by 359, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 359

Let's proceed to step 3:
When dividing 398 by 359, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 359 from 398, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 359

Advancing to step 4:
The number 359 fits into 395 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 36 after subtracting 359 from 395.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 359

Going ahead to step 5:
361 divided by 359 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 111.0
Subtracting 359 from 361 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 359

Going ahead to step 6:
If we divide 25 by 359, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
If we subtract 0 from 25, we get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 359

Advancing to step 7:
The number 359 fits into 259 0 times, leaving a remainder of 259.
Write down 0 as next digit of the result. 
Result so far: 11100.0
If we take 0 away from 259, we end up with 259.
Take the next digit (0) from the dividend and append it to 259, then repeat: 2590 / 359

Let's proceed to step 8:
359 can be fit into 2590 7 times, resulting in a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 111007.0
Deduct 2513 from 2590 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
If we divide 770 by 359, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 111007.2
Deduct 718 from 770 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 359 is 1 with a remainder of 161.
The number 1 becomes the next digit in our result. 
Result so far: 111007.21
If we subtract 359 from 520, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 11:
When dividing 1610 by 359, we get 4 with a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 111007.214
If we take 1436 away from 1610, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 12:
When dividing 1740 by 359, we get 4 with a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 111007.2144
Subtracting 1436 from 1740 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The quotient of the division is 111007.2144, and the remainder is 0.00304.
