3839574 ÷ 407 
Let's see how many times 407 fits into 3839574.

Let's proceed to step 1:
407 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 407

Let's proceed to step 2:
If we divide 38 by 407, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 407

Let's proceed to step 3:
383 divided by 407 is 0 with a remainder of 383.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 383 and we're left with 383.
Append the next digit (9) from the dividend to 383 and continue with: 3839 / 407

Advancing to step 4:
The number 407 fits into 3839 9 times, leaving a remainder of 176.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 3663 from 3839 and we're left with 176.
Fetch the next digit (5) from the dividend, attach it to 176 and continue: 1765 / 407

Step 5:
407 can be fit into 1765 4 times, resulting in a remainder of 137.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 1628 from 1765 and we're left with 137.
Bring next digit (7) of the dividend behind the 137 and repeat the process: 1377 / 407

On to step 6:
407 can be fit into 1377 3 times, resulting in a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 943.0
The remainder is 156 after subtracting 1221 from 1377.
Grab the next digit (4) from the dividend, add it to 156, then carry on: 1564 / 407

Let's proceed to step 7:
407 can be fit into 1564 3 times, resulting in a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 9433.0
Deduct 1221 from 1564 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 8:
407 goes into 3430 8 times with a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 9433.8
The remainder is 174 after subtracting 3256 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
If we divide 1740 by 407, we get 4 and a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 9433.84
If we subtract 1628 from 1740, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
407 goes into 1120 2 times with a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 9433.842
Subtracting 814 from 1120 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 11:
The number 407 fits into 3060 7 times, leaving a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 9433.8427
The remainder is 211 after subtracting 2849 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 12:
2110 divided by 407 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 9433.84275
Subtract 2035 from 2110 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
407 can be fit into 750 1 times, resulting in a remainder of 343.
The next digit of our result is 1. 
Result so far: 9433.842751
Subtracting 407 from 750 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 14:
The number 407 fits into 3430 8 times, leaving a remainder of 174.
The next digit of our result is 8. 
Result so far: 9433.8427518
If we take 3256 away from 3430, 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.

Step 15:
The number 407 fits into 1740 4 times, leaving a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 9433.84275184
If we take 1628 away from 1740, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 9433.84275184 and a remainder of 1.12e-07.
