We divide 12161979 by 19
We want to figure out the number of times 12161979 can be divided by 19.

Advancing to step 1:
19 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 19

Step 2:
The number 19 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 19

Moving on to step 3:
121 divided by 19 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 114 away from 121, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 19

Going ahead to step 4:
If we divide 76 by 19, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 76 away from 76, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 19

On to step 5:
When dividing 1 by 19, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 640.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 19

On to step 6:
The number 19 fits into 19 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 6401.0
Subtracting 19 from 19 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 19

Going ahead to step 7:
If we divide 7 by 19, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 64010.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 19

Moving on to step 8:
79 divided by 19 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 640104.0
Deduct 76 from 79 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 640104.1
If we take 19 away from 30, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 640104.15
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
150 divided by 19 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 640104.157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 640104.1578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
When dividing 180 by 19, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 640104.15789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
If we divide 90 by 19, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 640104.157894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
19 goes into 140 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 640104.1578947
Subtract 133 from 140 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 16:
70 divided by 19 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 640104.15789473
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 640104.15789473 with a remaining 1.3e-08.
