19391285 ÷ 122 
We're looking to find how many times 122 goes into 19391285.

Moving on to step 1:
122 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 122

Moving on to step 2:
The number 122 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 122

Let's proceed to step 3:
122 can be fit into 193 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 71 after subtracting 122 from 193.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 122

Going ahead to step 4:
The number 122 fits into 719 5 times, leaving a remainder of 109.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 610 from 719 leaves us with 109.
Fetch the next digit (1) from the dividend, attach it to 109 and continue: 1091 / 122

Advancing to step 5:
If we divide 1091 by 122, we get 8 and a remainder of 115.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 976 from 1091 to get 115.
Take the next digit (2) from the dividend and append it to 115, then repeat: 1152 / 122

Let's proceed to step 6:
If we divide 1152 by 122, we get 9 and a remainder of 54.
The next digit of our result is 9. 
Result so far: 1589.0
If we subtract 1098 from 1152, we get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 122

Going ahead to step 7:
If we divide 548 by 122, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 15894.0
Subtracting 488 from 548 leaves us with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 122

Going ahead to step 8:
122 goes into 605 4 times with a remainder of 117.
The next digit of our result is 4. 
Result so far: 158944.0
Subtracting 488 from 605 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
122 goes into 1170 9 times with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 158944.9
The remainder is 72 after subtracting 1098 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
The number 122 fits into 720 5 times, leaving a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 158944.95
Subtracting 610 from 720 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
The number 122 fits into 1100 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 158944.959
If we subtract 1098 from 1100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 122 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 158944.959
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
122 can be fit into 200 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 158944.95901
If we subtract 122 from 200, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
122 goes into 780 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 158944.959016
If we take 732 away from 780, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
122 goes into 480 3 times with a remainder of 114.
Use 3 as the next digit of our solution. 
Result so far: 158944.9590163
If we take 366 away from 480, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 16:
If we divide 1140 by 122, we get 9 and a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 158944.95901639
Deduct 1098 from 1140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 158944.95901639 with a balance of 4.2e-08.
