We look at the division of 77857993 by 149 
Let's see how many times 149 fits into 77857993.

Going ahead to step 1:
If we divide 7 by 149, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 149

Let's proceed to step 2:
149 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 149

Going ahead to step 3:
778 divided by 149 is 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 745 from 778 to get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 149

Let's proceed to step 4:
If we divide 335 by 149, we get 2 and a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 298 from 335, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 149

Let's proceed to step 5:
When dividing 377 by 149, we get 2 with a remainder of 79.
The next digit of our result is 2. 
Result so far: 522.0
Subtract 298 from 377 to get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 149

Moving on to step 6:
799 divided by 149 is 5 with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 5225.0
If we subtract 745 from 799, we get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 149

Advancing to step 7:
149 goes into 549 3 times with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 52253.0
The remainder is 102 after subtracting 447 from 549.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 149

Going ahead to step 8:
The number 149 fits into 1023 6 times, leaving a remainder of 129.
The number 6 becomes the next digit in our result. 
Result so far: 522536.0
If we take 894 away from 1023, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
When dividing 1290 by 149, we get 8 with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 522536.8
If we subtract 1192 from 1290, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
If we divide 980 by 149, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 522536.86
The remainder is 86 after subtracting 894 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
860 divided by 149 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 522536.865
The remainder is 115 after subtracting 745 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
149 can be fit into 1150 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 522536.8657
If we take 1043 away from 1150, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 13:
149 goes into 1070 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 522536.86577
Deduct 1043 from 1070 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 522536.86577 with a remainder of 2.7e-05.
