78200307 ÷ 149 
Let's see how many times 149 fits into 78200307.

Moving on 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 subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 149

Moving on to step 2:
When dividing 78 by 149, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 149

Going ahead to step 3:
149 goes into 782 5 times with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 745 from 782 to get 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 149

On to step 4:
370 divided by 149 is 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Deduct 298 from 370 and we're left with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 149

Going ahead to step 5:
When dividing 720 by 149, we get 4 with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 524.0
Deduct 596 from 720 and we're left with 124.
Take the next digit (3) from the dividend and append it to 124, then repeat: 1243 / 149

Going ahead to step 6:
149 can be fit into 1243 8 times, resulting in a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 5248.0
Subtract 1192 from 1243 to get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 149

Step 7:
149 goes into 510 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 52483.0
The remainder is 63 after subtracting 447 from 510.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 149

Going ahead to step 8:
637 divided by 149 is 4 with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 524834.0
The remainder is 41 after subtracting 596 from 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
If we divide 410 by 149, we get 2 and a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 524834.2
If we take 298 away from 410, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
149 goes into 1120 7 times with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 524834.27
If we subtract 1043 from 1120, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 11:
149 goes into 770 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 524834.275
Deduct 745 from 770 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
250 divided by 149 is 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 524834.2751
The remainder is 101 after subtracting 149 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 13:
When dividing 1010 by 149, we get 6 with a remainder of 116.
The next digit of our result is 6. 
Result so far: 524834.27516
Subtract 894 from 1010 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 14:
149 can be fit into 1160 7 times, resulting in a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 524834.275167
Subtracting 1043 from 1160 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 15:
The number 149 fits into 1170 7 times, leaving a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 524834.2751677
If we subtract 1043 from 1170, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final outcome is 524834.2751677, with a leftover of 1.27e-06.
