39400759 ÷ 844 
We want to figure out the number of times 39400759 can be divided by 844.

Step 1:
3 divided by 844 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 844

Step 2:
844 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 844

Step 3:
When dividing 394 by 844, we get 0 with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 394 and we're left with 394.
Append the next digit (0) from the dividend to 394 and continue with: 3940 / 844

Advancing to step 4:
The number 844 fits into 3940 4 times, leaving a remainder of 564.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3376 from 3940 to get 564.
Fetch the next digit (0) from the dividend, attach it to 564 and continue: 5640 / 844

Going ahead to step 5:
When dividing 5640 by 844, we get 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 5064 from 5640 to get 576.
Grab the next digit (7) from the dividend, add it to 576, then carry on: 5767 / 844

On to step 6:
5767 divided by 844 is 6 with a remainder of 703.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
If we take 5064 away from 5767, we end up with 703.
Fetch the next digit (5) from the dividend, attach it to 703 and continue: 7035 / 844

Going ahead to step 7:
The number 844 fits into 7035 8 times, leaving a remainder of 283.
The next digit of our result is 8. 
Result so far: 4668.0
Deduct 6752 from 7035 and we're left with 283.
Fetch the next digit (9) from the dividend, attach it to 283 and continue: 2839 / 844

On to step 8:
844 goes into 2839 3 times with a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 46683.0
Deduct 2532 from 2839 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Advancing to step 9:
844 goes into 3070 3 times with a remainder of 538.
Use 3 as the next digit of our solution. 
Result so far: 46683.3
Deduct 2532 from 3070 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 10:
844 goes into 5380 6 times with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 46683.36
The remainder is 316 after subtracting 5064 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 11:
844 can be fit into 3160 3 times, resulting in a remainder of 628.
Record the quotient 3 as the next digit in the result. 
Result so far: 46683.363
If we take 2532 away from 3160, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Step 12:
The number 844 fits into 6280 7 times, leaving a remainder of 372.
The next digit of our result is 7. 
Result so far: 46683.3637
If we subtract 5908 from 6280, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 13:
If we divide 3720 by 844, we get 4 and a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 46683.36374
Deduct 3376 from 3720 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 14:
When dividing 3440 by 844, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 46683.363744
Subtract 3376 from 3440 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 46683.363744 with a remaining 6.4e-06.
