We're dividing 19369819 by 158 
Let's see how many times 158 fits into 19369819.

Step 1:
If we divide 1 by 158, we get 0 and a remainder of 1.
The next digit of our result is 0. 
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 / 158

Let's proceed to step 2:
When dividing 19 by 158, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 158

Going ahead to step 3:
158 goes into 193 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 158 from 193 to get 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 158

Step 4:
356 divided by 158 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 316 from 356 and we're left with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 158

Step 5:
If we divide 409 by 158, we get 2 and a remainder of 93.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Deduct 316 from 409 and we're left with 93.
Take the next digit (8) from the dividend and append it to 93, then repeat: 938 / 158

On to step 6:
When dividing 938 by 158, we get 5 with a remainder of 148.
Write down 5 as next digit of the result. 
Result so far: 1225.0
If we subtract 790 from 938, we get 148.
Append the next digit (1) from the dividend to 148 and continue with: 1481 / 158

Going ahead to step 7:
158 goes into 1481 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 12259.0
Deduct 1422 from 1481 and we're left with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 158

Going ahead to step 8:
158 can be fit into 599 3 times, resulting in a remainder of 125.
Use 3 as the next digit of our solution. 
Result so far: 122593.0
If we take 474 away from 599, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
If we divide 1250 by 158, we get 7 and a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 122593.7
If we take 1106 away from 1250, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
158 goes into 1440 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 122593.79
Subtracting 1422 from 1440 leaves us 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.

Going ahead to step 11:
158 can be fit into 180 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 122593.791
If we take 158 away from 180, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
The number 158 fits into 220 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 122593.7911
Subtracting 158 from 220 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 122593.7911, and the remainder is 0.00062.
