72972948 ÷ 423 
Let's see how many times 423 fits into 72972948.

Advancing to step 1:
423 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 423

Advancing to step 2:
The number 423 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 423

Going ahead to step 3:
If we divide 729 by 423, we get 1 and a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 306 after subtracting 423 from 729.
Bring next digit (7) of the dividend behind the 306 and repeat the process: 3067 / 423

On to step 4:
When dividing 3067 by 423, we get 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 2961 from 3067, we get 106.
Bring next digit (2) of the dividend behind the 106 and repeat the process: 1062 / 423

Advancing to step 5:
The number 423 fits into 1062 2 times, leaving a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtract 846 from 1062 to get 216.
Take the next digit (9) from the dividend and append it to 216, then repeat: 2169 / 423

On to step 6:
423 can be fit into 2169 5 times, resulting in a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 1725.0
Subtract 2115 from 2169 to get 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 423

Moving on to step 7:
423 goes into 544 1 times with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 17251.0
If we take 423 away from 544, we end up with 121.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 423

Let's proceed to step 8:
1218 divided by 423 is 2 with a remainder of 372.
The next digit of our result is 2. 
Result so far: 172512.0
Subtracting 846 from 1218 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 9:
3720 divided by 423 is 8 with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 172512.8
Subtracting 3384 from 3720 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
When dividing 3360 by 423, we get 7 with a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 172512.87
Deduct 2961 from 3360 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 11:
If we divide 3990 by 423, we get 9 and a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 172512.879
If we subtract 3807 from 3990, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 12:
The number 423 fits into 1830 4 times, leaving a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 172512.8794
Deduct 1692 from 1830 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 13:
The number 423 fits into 1380 3 times, leaving a remainder of 111.
The next digit of our result is 3. 
Result so far: 172512.87943
If we subtract 1269 from 1380, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 14:
1110 divided by 423 is 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 172512.879432
If we take 846 away from 1110, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 15:
When dividing 2640 by 423, we get 6 with a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 172512.8794326
If we subtract 2538 from 2640, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 16:
1020 divided by 423 is 2 with a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 172512.87943262
If we subtract 846 from 1020, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Our division results in 172512.87943262 with a remaining 1.74e-07.
