We divide 72439351 by 403
We want to divide 72439351 by 403.

On to step 1:
403 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 403

Step 2:
If we divide 72 by 403, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (4) from the dividend, add it to 72, then carry on: 724 / 403

Advancing to step 3:
If we divide 724 by 403, we get 1 and a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 403 away from 724, we end up with 321.
Bring next digit (3) of the dividend behind the 321 and repeat the process: 3213 / 403

Going ahead to step 4:
403 can be fit into 3213 7 times, resulting in a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2821 from 3213, we get 392.
Take the next digit (9) from the dividend and append it to 392, then repeat: 3929 / 403

Let's proceed to step 5:
If we divide 3929 by 403, we get 9 and a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
Subtract 3627 from 3929 to get 302.
Bring next digit (3) of the dividend behind the 302 and repeat the process: 3023 / 403

Advancing to step 6:
3023 divided by 403 is 7 with a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 1797.0
The remainder is 202 after subtracting 2821 from 3023.
Take the next digit (5) from the dividend and append it to 202, then repeat: 2025 / 403

Step 7:
The number 403 fits into 2025 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17975.0
Deduct 2015 from 2025 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 403

Let's proceed to step 8:
When dividing 101 by 403, we get 0 with a remainder of 101.
The next digit of our result is 0. 
Result so far: 179750.0
Subtracting 0 from 101 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
403 goes into 1010 2 times with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 179750.2
Deduct 806 from 1010 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
403 goes into 2040 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 179750.25
The remainder is 25 after subtracting 2015 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
403 can be fit into 250 0 times, resulting in a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 179750.25
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
If we divide 2500 by 403, we get 6 and a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 179750.2506
Deduct 2418 from 2500 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 13:
403 goes into 820 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 179750.25062
If we subtract 806 from 820, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
If we divide 140 by 403, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 179750.25062
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
The number 403 fits into 1400 3 times, leaving a remainder of 191.
The next digit of our result is 3. 
Result so far: 179750.2506203
Deduct 1209 from 1400 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 16:
When dividing 1910 by 403, we get 4 with a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 179750.25062034
Subtract 1612 from 1910 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

After the division, we end up with 179750.25062034 and a remainder of 2.98e-07.
