39399643 divided by 889 
Our goal is to divide 39399643 by 889.

On to step 1:
If we divide 3 by 889, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 889

Going ahead to step 2:
889 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 889

On to step 3:
The number 889 fits into 393 0 times, leaving a remainder of 393.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Grab the next digit (9) from the dividend, add it to 393, then carry on: 3939 / 889

Let's proceed to step 4:
When dividing 3939 by 889, we get 4 with a remainder of 383.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3556 from 3939 and we're left with 383.
Include the next digit (9) from the dividend after 383, then repeat: 3839 / 889

On to step 5:
3839 divided by 889 is 4 with a remainder of 283.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 3556 from 3839, we get 283.
Take the next digit (6) from the dividend and append it to 283, then repeat: 2836 / 889

Going ahead to step 6:
889 can be fit into 2836 3 times, resulting in a remainder of 169.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
If we take 2667 away from 2836, we end up with 169.
Fetch the next digit (4) from the dividend, attach it to 169 and continue: 1694 / 889

Step 7:
The number 889 fits into 1694 1 times, leaving a remainder of 805.
The next digit of our result is 1. 
Result so far: 4431.0
The remainder is 805 after subtracting 889 from 1694.
Take the next digit (3) from the dividend and append it to 805, then repeat: 8053 / 889

Going ahead to step 8:
889 can be fit into 8053 9 times, resulting in a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 44319.0
Subtract 8001 from 8053 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
520 divided by 889 is 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 44319.0
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
When dividing 5200 by 889, we get 5 with a remainder of 755.
The next digit of our result is 5. 
Result so far: 44319.05
Subtracting 4445 from 5200 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 11:
The number 889 fits into 7550 8 times, leaving a remainder of 438.
The number 8 becomes the next digit in our result. 
Result so far: 44319.058
The remainder is 438 after subtracting 7112 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 12:
889 goes into 4380 4 times with a remainder of 824.
Put 4 as the next digit of the answer. 
Result so far: 44319.0584
If we take 3556 away from 4380, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 13:
889 goes into 8240 9 times with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 44319.05849
Subtract 8001 from 8240 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 14:
The number 889 fits into 2390 2 times, leaving a remainder of 612.
The number 2 becomes the next digit in our result. 
Result so far: 44319.058492
Subtracting 1778 from 2390 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 15:
The number 889 fits into 6120 6 times, leaving a remainder of 786.
The next digit of our result is 6. 
Result so far: 44319.0584926
If we subtract 5334 from 6120, we get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 16:
If we divide 7860 by 889, we get 8 and a remainder of 748.
The number 8 becomes the next digit in our result. 
Result so far: 44319.05849268
Subtracting 7112 from 7860 leaves us with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

The final outcome is 44319.05849268, with a leftover of 7.48e-07.
