We divide 66016532 by 403
Our goal is to divide 66016532 by 403.

Advancing to step 1:
6 divided by 403 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 403

Advancing to step 2:
If we divide 66 by 403, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 403

On to step 3:
If we divide 660 by 403, we get 1 and a remainder of 257.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 403 from 660 to get 257.
Append the next digit (1) from the dividend to 257 and continue with: 2571 / 403

Let's proceed to step 4:
403 goes into 2571 6 times with a remainder of 153.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 2418 from 2571 and we're left with 153.
Grab the next digit (6) from the dividend, add it to 153, then carry on: 1536 / 403

On to step 5:
The number 403 fits into 1536 3 times, leaving a remainder of 327.
The next digit of our result is 3. 
Result so far: 163.0
If we take 1209 away from 1536, we end up with 327.
Append the next digit (5) from the dividend to 327 and continue with: 3275 / 403

Going ahead to step 6:
403 can be fit into 3275 8 times, resulting in a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 1638.0
The remainder is 51 after subtracting 3224 from 3275.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 403

Step 7:
403 can be fit into 513 1 times, resulting in a remainder of 110.
The next digit of our result is 1. 
Result so far: 16381.0
Deduct 403 from 513 and we're left with 110.
Bring next digit (2) of the dividend behind the 110 and repeat the process: 1102 / 403

Moving on to step 8:
403 goes into 1102 2 times with a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 163812.0
The remainder is 296 after subtracting 806 from 1102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 9:
The number 403 fits into 2960 7 times, leaving a remainder of 139.
The next digit of our result is 7. 
Result so far: 163812.7
Subtracting 2821 from 2960 leaves us 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:
1390 divided by 403 is 3 with a remainder of 181.
The number 3 becomes the next digit in our result. 
Result so far: 163812.73
If we take 1209 away from 1390, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 11:
The number 403 fits into 1810 4 times, leaving a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 163812.734
Deduct 1612 from 1810 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 12:
403 can be fit into 1980 4 times, resulting in a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 163812.7344
Subtracting 1612 from 1980 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 163812.7344 with a remainder of 0.00368.
