3924237 divided by 724 
Our goal is to divide 3924237 by 724.

Advancing to step 1:
If we divide 3 by 724, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 724

Step 2:
When dividing 39 by 724, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 724

Step 3:
When dividing 392 by 724, we get 0 with a remainder of 392.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Take the next digit (4) from the dividend and append it to 392, then repeat: 3924 / 724

On to step 4:
The number 724 fits into 3924 5 times, leaving a remainder of 304.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 304 after subtracting 3620 from 3924.
Bring next digit (2) of the dividend behind the 304 and repeat the process: 3042 / 724

Going ahead to step 5:
3042 divided by 724 is 4 with a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 146 after subtracting 2896 from 3042.
Fetch the next digit (3) from the dividend, attach it to 146 and continue: 1463 / 724

Step 6:
When dividing 1463 by 724, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 542.0
Deduct 1448 from 1463 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 724

Going ahead to step 7:
157 divided by 724 is 0 with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 5420.0
The remainder is 157 after subtracting 0 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 8:
724 goes into 1570 2 times with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 5420.2
Subtracting 1448 from 1570 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 9:
When dividing 1220 by 724, we get 1 with a remainder of 496.
Use 1 as the next digit of our solution. 
Result so far: 5420.21
Subtracting 724 from 1220 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 10:
724 goes into 4960 6 times with a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 5420.216
Deduct 4344 from 4960 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 11:
The number 724 fits into 6160 8 times, leaving a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 5420.2168
Deduct 5792 from 6160 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
The number 724 fits into 3680 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 5420.21685
Subtracting 3620 from 3680 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
724 goes into 600 0 times with a remainder of 600.
The next digit of our result is 0. 
Result so far: 5420.21685
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 14:
6000 divided by 724 is 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 5420.2168508
Subtract 5792 from 6000 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
If we divide 2080 by 724, we get 2 and a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 5420.21685082
Subtract 1448 from 2080 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final outcome is 5420.21685082, with a leftover of 6.32e-07.
