20559861 divided by 478 
We want to figure out the number of times 20559861 can be divided by 478.

On to step 1:
The number 478 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 478

Let's proceed to step 2:
478 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 478

Moving on to step 3:
The number 478 fits into 205 0 times, leaving a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Take the next digit (5) from the dividend and append it to 205, then repeat: 2055 / 478

Let's proceed to step 4:
When dividing 2055 by 478, we get 4 with a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 143 after subtracting 1912 from 2055.
Fetch the next digit (9) from the dividend, attach it to 143 and continue: 1439 / 478

On to step 5:
The number 478 fits into 1439 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 1434 from 1439 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 478

Advancing to step 6:
478 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
If we take 0 away from 58, we end up with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 478

Let's proceed to step 7:
The number 478 fits into 586 1 times, leaving a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 4301.0
Deduct 478 from 586 and we're left with 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 478

Advancing to step 8:
The number 478 fits into 1081 2 times, leaving a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 43012.0
Deduct 956 from 1081 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 9:
If we divide 1250 by 478, we get 2 and a remainder of 294.
The next digit of our result is 2. 
Result so far: 43012.2
The remainder is 294 after subtracting 956 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
When dividing 2940 by 478, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 43012.26
If we take 2868 away from 2940, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
When dividing 720 by 478, we get 1 with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 43012.261
If we subtract 478 from 720, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
478 can be fit into 2420 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 43012.2615
Deduct 2390 from 2420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 478 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 43012.2615
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
The number 478 fits into 3000 6 times, leaving a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 43012.261506
If we take 2868 away from 3000, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 15:
478 goes into 1320 2 times with a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 43012.2615062
If we take 956 away from 1320, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 16:
If we divide 3640 by 478, we get 7 and a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 43012.26150627
If we take 3346 away from 3640, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The final result is 43012.26150627 with a remainder of 2.94e-07.
