12355420 divided by 806 
We want to figure out the number of times 12355420 can be divided by 806.

Step 1:
If we divide 1 by 806, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 806

Moving on to step 2:
806 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 806

Step 3:
When dividing 123 by 806, we get 0 with a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Include the next digit (5) from the dividend after 123, then repeat: 1235 / 806

Let's proceed to step 4:
When dividing 1235 by 806, we get 1 with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 806 from 1235 to get 429.
Take the next digit (5) from the dividend and append it to 429, then repeat: 4295 / 806

Let's proceed to step 5:
4295 divided by 806 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 4030 from 4295 leaves us with 265.
Take the next digit (4) from the dividend and append it to 265, then repeat: 2654 / 806

Moving on to step 6:
When dividing 2654 by 806, we get 3 with a remainder of 236.
The next digit of our result is 3. 
Result so far: 153.0
If we take 2418 away from 2654, we end up with 236.
Grab the next digit (2) from the dividend, add it to 236, then carry on: 2362 / 806

Moving on to step 7:
806 can be fit into 2362 2 times, resulting in a remainder of 750.
The number 2 becomes the next digit in our result. 
Result so far: 1532.0
If we take 1612 away from 2362, we end up with 750.
Grab the next digit (0) from the dividend, add it to 750, then carry on: 7500 / 806

Moving on to step 8:
If we divide 7500 by 806, we get 9 and a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 15329.0
The remainder is 246 after subtracting 7254 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 9:
If we divide 2460 by 806, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 15329.3
Subtract 2418 from 2460 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
When dividing 420 by 806, we get 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 15329.3
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
806 goes into 4200 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 15329.305
If we take 4030 away from 4200, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
1700 divided by 806 is 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 15329.3052
Subtracting 1612 from 1700 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
When dividing 880 by 806, we get 1 with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 15329.30521
Deduct 806 from 880 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 14:
740 divided by 806 is 0 with a remainder of 740.
Use 0 as the next digit of our solution. 
Result so far: 15329.30521
If we take 0 away from 740, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 15:
806 goes into 7400 9 times with a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 15329.3052109
If we subtract 7254 from 7400, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 16:
806 goes into 1460 1 times with a remainder of 654.
The number 1 becomes the next digit in our result. 
Result so far: 15329.30521091
If we take 806 away from 1460, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

In conclusion, the division gives 15329.30521091 with a balance of 6.54e-07.
