19878534 ÷ 470 
We want to divide 19878534 by 470.

Advancing to step 1:
1 divided by 470 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 470

Step 2:
The number 470 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 470

Moving on to step 3:
If we divide 198 by 470, we get 0 and a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 198, we end up with 198.
Include the next digit (7) from the dividend after 198, then repeat: 1987 / 470

Step 4:
470 can be fit into 1987 4 times, resulting in a remainder of 107.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1880 away from 1987, we end up with 107.
Grab the next digit (8) from the dividend, add it to 107, then carry on: 1078 / 470

Advancing to step 5:
If we divide 1078 by 470, we get 2 and a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 940 away from 1078, we end up with 138.
Take the next digit (5) from the dividend and append it to 138, then repeat: 1385 / 470

Advancing to step 6:
470 goes into 1385 2 times with a remainder of 445.
Write down 2 as next digit of the result. 
Result so far: 422.0
Subtract 940 from 1385 to get 445.
Fetch the next digit (3) from the dividend, attach it to 445 and continue: 4453 / 470

Going ahead to step 7:
The number 470 fits into 4453 9 times, leaving a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 4229.0
If we subtract 4230 from 4453, we get 223.
Include the next digit (4) from the dividend after 223, then repeat: 2234 / 470

Advancing to step 8:
2234 divided by 470 is 4 with a remainder of 354.
The number 4 becomes the next digit in our result. 
Result so far: 42294.0
If we subtract 1880 from 2234, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
3540 divided by 470 is 7 with a remainder of 250.
Use 7 as the next digit of our solution. 
Result so far: 42294.7
Deduct 3290 from 3540 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
470 goes into 2500 5 times with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 42294.75
Deduct 2350 from 2500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
1500 divided by 470 is 3 with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 42294.753
The remainder is 90 after subtracting 1410 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
When dividing 900 by 470, we get 1 with a remainder of 430.
Write down 1 as next digit of the result. 
Result so far: 42294.7531
If we take 470 away from 900, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 13:
If we divide 4300 by 470, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 42294.75319
Subtract 4230 from 4300 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
470 goes into 700 1 times with a remainder of 230.
The number 1 becomes the next digit in our result. 
Result so far: 42294.753191
If we subtract 470 from 700, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 15:
The number 470 fits into 2300 4 times, leaving a remainder of 420.
The number 4 becomes the next digit in our result. 
Result so far: 42294.7531914
If we take 1880 away from 2300, we end up 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 16:
If we divide 4200 by 470, we get 8 and a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 42294.75319148
The remainder is 440 after subtracting 3760 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 42294.75319148, with a leftover of 4.4e-07.
