We're dividing 66196274 by 479 
Let's see how many times 479 fits into 66196274.

On to step 1:
The number 479 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 479

Step 2:
When dividing 66 by 479, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 479

Step 3:
479 can be fit into 661 1 times, resulting in a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 182 after subtracting 479 from 661.
Take the next digit (9) from the dividend and append it to 182, then repeat: 1829 / 479

Let's proceed to step 4:
When dividing 1829 by 479, we get 3 with a remainder of 392.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1437 from 1829 to get 392.
Include the next digit (6) from the dividend after 392, then repeat: 3926 / 479

Going ahead to step 5:
When dividing 3926 by 479, we get 8 with a remainder of 94.
Put 8 as the next digit of the answer. 
Result so far: 138.0
The remainder is 94 after subtracting 3832 from 3926.
Bring next digit (2) of the dividend behind the 94 and repeat the process: 942 / 479

On to step 6:
If we divide 942 by 479, we get 1 and a remainder of 463.
Put 1 as the next digit of the answer. 
Result so far: 1381.0
If we take 479 away from 942, we end up with 463.
Include the next digit (7) from the dividend after 463, then repeat: 4637 / 479

On to step 7:
If we divide 4637 by 479, we get 9 and a remainder of 326.
Use 9 as the next digit of our solution. 
Result so far: 13819.0
Deduct 4311 from 4637 and we're left with 326.
Include the next digit (4) from the dividend after 326, then repeat: 3264 / 479

Going ahead to step 8:
479 goes into 3264 6 times with a remainder of 390.
Record the quotient 6 as the next digit in the result. 
Result so far: 138196.0
If we take 2874 away from 3264, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 9:
479 can be fit into 3900 8 times, resulting in a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 138196.8
Deduct 3832 from 3900 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
When dividing 680 by 479, we get 1 with a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 138196.81
If we subtract 479 from 680, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 11:
2010 divided by 479 is 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 138196.814
If we subtract 1916 from 2010, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
When dividing 940 by 479, we get 1 with a remainder of 461.
The next digit of our result is 1. 
Result so far: 138196.8141
Deduct 479 from 940 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 13:
479 goes into 4610 9 times with a remainder of 299.
Put 9 as the next digit of the answer. 
Result so far: 138196.81419
Subtract 4311 from 4610 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 14:
When dividing 2990 by 479, we get 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 138196.814196
Subtracting 2874 from 2990 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 15:
1160 divided by 479 is 2 with a remainder of 202.
The next digit of our result is 2. 
Result so far: 138196.8141962
If we subtract 958 from 1160, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 16:
479 can be fit into 2020 4 times, resulting in a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 138196.81419624
Subtract 1916 from 2020 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 138196.81419624 and a remainder of 1.04e-07.
