We're dividing 19914980 by 439 
We want to divide 19914980 by 439.

Let's proceed to step 1:
439 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 439

Moving on to step 2:
When dividing 19 by 439, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 439

Moving on to step 3:
When dividing 199 by 439, we get 0 with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 199 and we're left with 199.
Take the next digit (1) from the dividend and append it to 199, then repeat: 1991 / 439

Let's proceed to step 4:
439 goes into 1991 4 times with a remainder of 235.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1756 from 1991 leaves us with 235.
Append the next digit (4) from the dividend to 235 and continue with: 2354 / 439

Moving on to step 5:
439 can be fit into 2354 5 times, resulting in a remainder of 159.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 2195 from 2354, we get 159.
Take the next digit (9) from the dividend and append it to 159, then repeat: 1599 / 439

Moving on to step 6:
1599 divided by 439 is 3 with a remainder of 282.
The next digit of our result is 3. 
Result so far: 453.0
If we subtract 1317 from 1599, we get 282.
Append the next digit (8) from the dividend to 282 and continue with: 2828 / 439

Moving on to step 7:
439 can be fit into 2828 6 times, resulting in a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 4536.0
Subtracting 2634 from 2828 leaves us with 194.
Take the next digit (0) from the dividend and append it to 194, then repeat: 1940 / 439

Let's proceed to step 8:
If we divide 1940 by 439, we get 4 and a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 45364.0
Deduct 1756 from 1940 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
The number 439 fits into 1840 4 times, leaving a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 45364.4
Subtract 1756 from 1840 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
439 can be fit into 840 1 times, resulting in a remainder of 401.
Record the quotient 1 as the next digit in the result. 
Result so far: 45364.41
The remainder is 401 after subtracting 439 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 11:
4010 divided by 439 is 9 with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 45364.419
Deduct 3951 from 4010 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 12:
439 can be fit into 590 1 times, resulting in a remainder of 151.
The next digit of our result is 1. 
Result so far: 45364.4191
If we take 439 away from 590, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 13:
When dividing 1510 by 439, we get 3 with a remainder of 193.
The next digit of our result is 3. 
Result so far: 45364.41913
If we take 1317 away from 1510, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 14:
439 goes into 1930 4 times with a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 45364.419134
Subtract 1756 from 1930 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 15:
439 can be fit into 1740 3 times, resulting in a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 45364.4191343
Subtracting 1317 from 1740 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 16:
439 goes into 4230 9 times with a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 45364.41913439
If we subtract 3951 from 4230, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Our division results in 45364.41913439 with a remaining 2.79e-07.
