We divide 149902 by 78
We want to figure out the number of times 149902 can be divided by 78.

Going ahead to step 1:
78 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 78

On to step 2:
78 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 78

Moving on to step 3:
149 divided by 78 is 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 149 leaves us with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 78

Let's proceed to step 4:
When dividing 719 by 78, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 702 away from 719, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 78

Advancing to step 5:
78 goes into 170 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
Subtract 156 from 170 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 78

On to step 6:
78 goes into 142 1 times with a remainder of 64.
The next digit of our result is 1. 
Result so far: 1921.0
If we subtract 78 from 142, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
640 divided by 78 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 1921.8
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
78 goes into 160 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1921.82
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1921.82
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
If we divide 400 by 78, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1921.8205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 78, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1921.82051
Subtracting 78 from 100 leaves us 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.

Advancing to step 12:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 1921.820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
If we divide 640 by 78, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1921.8205128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 1921.82051282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 1921.82051282, and the remainder is 4e-09.
