40151209 ÷ 194 
We're looking to find how many times 194 goes into 40151209.

Moving on to step 1:
When dividing 4 by 194, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 194

Going ahead to step 2:
When dividing 40 by 194, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 194

Going ahead to step 3:
194 goes into 401 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 388 from 401 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 194

Advancing to step 4:
194 can be fit into 135 0 times, resulting in a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 135, we get 135.
Fetch the next digit (1) from the dividend, attach it to 135 and continue: 1351 / 194

Moving on to step 5:
The number 194 fits into 1351 6 times, leaving a remainder of 187.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
If we subtract 1164 from 1351, we get 187.
Append the next digit (2) from the dividend to 187 and continue with: 1872 / 194

Advancing to step 6:
If we divide 1872 by 194, we get 9 and a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 2069.0
Deduct 1746 from 1872 and we're left with 126.
Fetch the next digit (0) from the dividend, attach it to 126 and continue: 1260 / 194

Going ahead to step 7:
If we divide 1260 by 194, we get 6 and a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 20696.0
If we take 1164 away from 1260, we end up with 96.
Take the next digit (9) from the dividend and append it to 96, then repeat: 969 / 194

On to step 8:
The number 194 fits into 969 4 times, leaving a remainder of 193.
Write down 4 as next digit of the result. 
Result so far: 206964.0
If we subtract 776 from 969, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
194 can be fit into 1930 9 times, resulting in a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 206964.9
If we subtract 1746 from 1930, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
194 goes into 1840 9 times with a remainder of 94.
The next digit of our result is 9. 
Result so far: 206964.99
If we subtract 1746 from 1840, 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.

The final result is 206964.99 with a remainder of 0.094.
