We're dividing 66878798 by 149 
We're looking to find how many times 149 goes into 66878798.

On to step 1:
6 divided by 149 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 149

Moving on to step 2:
When dividing 66 by 149, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 149

Let's proceed to step 3:
When dividing 668 by 149, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 596 from 668, we get 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 149

Step 4:
If we divide 727 by 149, we get 4 and a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 596 away from 727, we end up with 131.
Append the next digit (8) from the dividend to 131 and continue with: 1318 / 149

Going ahead to step 5:
The number 149 fits into 1318 8 times, leaving a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 448.0
The remainder is 126 after subtracting 1192 from 1318.
Grab the next digit (7) from the dividend, add it to 126, then carry on: 1267 / 149

Going ahead to step 6:
1267 divided by 149 is 8 with a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 4488.0
Deduct 1192 from 1267 and we're left with 75.
Append the next digit (9) from the dividend to 75 and continue with: 759 / 149

Let's proceed to step 7:
If we divide 759 by 149, we get 5 and a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 44885.0
Deduct 745 from 759 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 149

Advancing to step 8:
149 can be fit into 148 0 times, resulting in a remainder of 148.
Put 0 as the next digit of the answer. 
Result so far: 448850.0
If we subtract 0 from 148, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
149 goes into 1480 9 times with a remainder of 139.
Use 9 as the next digit of our solution. 
Result so far: 448850.9
Deduct 1341 from 1480 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
When dividing 1390 by 149, we get 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 448850.99
Subtract 1341 from 1390 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 448850.99 and a remainder of 0.049.
