Let's divide 39393435 by 423
We're looking to find how many times 423 goes into 39393435.

Advancing to step 1:
423 goes into 3 0 times 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.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 423

Step 2:
The number 423 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 423

On to step 3:
If we divide 393 by 423, we get 0 and a remainder of 393.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Include the next digit (9) from the dividend after 393, then repeat: 3939 / 423

Let's proceed to step 4:
If we divide 3939 by 423, we get 9 and a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 3807 away from 3939, we end up with 132.
Append the next digit (3) from the dividend to 132 and continue with: 1323 / 423

Let's proceed to step 5:
1323 divided by 423 is 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 1269 from 1323 to get 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 423

Moving on to step 6:
If we divide 544 by 423, we get 1 and a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 931.0
If we subtract 423 from 544, we get 121.
Bring next digit (3) of the dividend behind the 121 and repeat the process: 1213 / 423

Let's proceed to step 7:
423 can be fit into 1213 2 times, resulting in a remainder of 367.
The next digit of our result is 2. 
Result so far: 9312.0
If we subtract 846 from 1213, we get 367.
Append the next digit (5) from the dividend to 367 and continue with: 3675 / 423

Moving on to step 8:
When dividing 3675 by 423, we get 8 with a remainder of 291.
The next digit of our result is 8. 
Result so far: 93128.0
If we subtract 3384 from 3675, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 9:
The number 423 fits into 2910 6 times, leaving a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 93128.6
Deduct 2538 from 2910 and we're left 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.

Let's proceed to step 10:
423 goes into 3720 8 times with a remainder of 336.
The next digit of our result is 8. 
Result so far: 93128.68
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.

Step 11:
If we divide 3360 by 423, we get 7 and a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 93128.687
Subtracting 2961 from 3360 leaves us 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.

Advancing to step 12:
3990 divided by 423 is 9 with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 93128.6879
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.

Going ahead to step 13:
423 goes into 1830 4 times with a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 93128.68794
If we take 1692 away from 1830, we end up 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.

Let's proceed to step 14:
When dividing 1380 by 423, we get 3 with a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 93128.687943
The remainder is 111 after subtracting 1269 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 15:
The number 423 fits into 1110 2 times, leaving a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 93128.6879432
Deduct 846 from 1110 and we're left 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.

On to step 16:
The number 423 fits into 2640 6 times, leaving a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 93128.68794326
Deduct 2538 from 2640 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 93128.68794326 with a remainder of 1.02e-07.
