12373032 divided by 428 
Our goal is to divide 12373032 by 428.

Let's proceed to step 1:
When dividing 1 by 428, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 428

Let's proceed to step 2:
The number 428 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 428

Let's proceed to step 3:
428 can be fit into 123 0 times, resulting in a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Fetch the next digit (7) from the dividend, attach it to 123 and continue: 1237 / 428

On to step 4:
The number 428 fits into 1237 2 times, leaving a remainder of 381.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 856 from 1237 leaves us with 381.
Fetch the next digit (3) from the dividend, attach it to 381 and continue: 3813 / 428

Moving on to step 5:
428 goes into 3813 8 times with a remainder of 389.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 3424 from 3813 to get 389.
Grab the next digit (0) from the dividend, add it to 389, then carry on: 3890 / 428

Going ahead to step 6:
The number 428 fits into 3890 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
If we take 3852 away from 3890, we end up with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 428

On to step 7:
The number 428 fits into 383 0 times, leaving a remainder of 383.
Use 0 as the next digit of our solution. 
Result so far: 2890.0
If we subtract 0 from 383, we get 383.
Take the next digit (2) from the dividend and append it to 383, then repeat: 3832 / 428

On to step 8:
When dividing 3832 by 428, we get 8 with a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 28908.0
Subtracting 3424 from 3832 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 9:
The number 428 fits into 4080 9 times, leaving a remainder of 228.
The number 9 becomes the next digit in our result. 
Result so far: 28908.9
Subtract 3852 from 4080 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 10:
428 can be fit into 2280 5 times, resulting in a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 28908.95
Subtracting 2140 from 2280 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.

Going ahead to step 11:
The number 428 fits into 1400 3 times, leaving a remainder of 116.
The next digit of our result is 3. 
Result so far: 28908.953
Subtract 1284 from 1400 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
When dividing 1160 by 428, we get 2 with a remainder of 304.
The next digit of our result is 2. 
Result so far: 28908.9532
If we take 856 away from 1160, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 13:
When dividing 3040 by 428, we get 7 with a remainder of 44.
The next digit of our result is 7. 
Result so far: 28908.95327
If we take 2996 away from 3040, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
If we divide 440 by 428, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 28908.953271
Subtracting 428 from 440 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
The number 428 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 28908.953271
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
428 goes into 1200 2 times with a remainder of 344.
Write down 2 as next digit of the result. 
Result so far: 28908.95327102
The remainder is 344 after subtracting 856 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 28908.95327102, with a leftover of 3.44e-07.
