We're dividing 76404208 by 603 
We want to divide 76404208 by 603.

Step 1:
603 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 603

Going ahead to step 2:
The number 603 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 603

Step 3:
603 goes into 764 1 times with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 603 from 764 and we're left with 161.
Append the next digit (0) from the dividend to 161 and continue with: 1610 / 603

On to step 4:
The number 603 fits into 1610 2 times, leaving a remainder of 404.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1206 from 1610 to get 404.
Append the next digit (4) from the dividend to 404 and continue with: 4044 / 603

Going ahead to step 5:
603 can be fit into 4044 6 times, resulting in a remainder of 426.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 3618 from 4044 and we're left with 426.
Include the next digit (2) from the dividend after 426, then repeat: 4262 / 603

Advancing to step 6:
603 can be fit into 4262 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 1267.0
If we take 4221 away from 4262, we end up with 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 603

Step 7:
The number 603 fits into 410 0 times, leaving a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 12670.0
If we subtract 0 from 410, we get 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 603

Let's proceed to step 8:
If we divide 4108 by 603, we get 6 and a remainder of 490.
Put 6 as the next digit of the answer. 
Result so far: 126706.0
Subtracting 3618 from 4108 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 9:
The number 603 fits into 4900 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 126706.8
Deduct 4824 from 4900 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
603 can be fit into 760 1 times, resulting in a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 126706.81
Subtracting 603 from 760 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 11:
603 can be fit into 1570 2 times, resulting in a remainder of 364.
The next digit of our result is 2. 
Result so far: 126706.812
Subtracting 1206 from 1570 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 12:
3640 divided by 603 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 126706.8126
Subtract 3618 from 3640 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 603, we get 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 126706.8126
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
603 goes into 2200 3 times with a remainder of 391.
Use 3 as the next digit of our solution. 
Result so far: 126706.812603
Deduct 1809 from 2200 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 15:
The number 603 fits into 3910 6 times, leaving a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 126706.8126036
If we take 3618 away from 3910, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 16:
603 can be fit into 2920 4 times, resulting in a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 126706.81260364
If we take 2412 away from 2920, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The final outcome is 126706.81260364, with a leftover of 5.08e-07.
