66635438 ÷ 381 
We want to divide 66635438 by 381.

Let's proceed to step 1:
381 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 381

Step 2:
When dividing 66 by 381, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 381

Let's proceed to step 3:
666 divided by 381 is 1 with a remainder of 285.
The next digit of our result is 1. 
Result so far: 1.0
If we take 381 away from 666, we end up with 285.
Grab the next digit (3) from the dividend, add it to 285, then carry on: 2853 / 381

Let's proceed to step 4:
381 goes into 2853 7 times with a remainder of 186.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2667 away from 2853, we end up with 186.
Append the next digit (5) from the dividend to 186 and continue with: 1865 / 381

Going ahead to step 5:
The number 381 fits into 1865 4 times, leaving a remainder of 341.
Put 4 as the next digit of the answer. 
Result so far: 174.0
The remainder is 341 after subtracting 1524 from 1865.
Fetch the next digit (4) from the dividend, attach it to 341 and continue: 3414 / 381

Advancing to step 6:
If we divide 3414 by 381, we get 8 and a remainder of 366.
The next digit of our result is 8. 
Result so far: 1748.0
The remainder is 366 after subtracting 3048 from 3414.
Fetch the next digit (3) from the dividend, attach it to 366 and continue: 3663 / 381

Step 7:
The number 381 fits into 3663 9 times, leaving a remainder of 234.
Put 9 as the next digit of the answer. 
Result so far: 17489.0
Subtract 3429 from 3663 to get 234.
Append the next digit (8) from the dividend to 234 and continue with: 2348 / 381

Moving on to step 8:
The number 381 fits into 2348 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 174896.0
If we subtract 2286 from 2348, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
381 can be fit into 620 1 times, resulting in a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 174896.1
If we subtract 381 from 620, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 10:
When dividing 2390 by 381, we get 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 174896.16
If we subtract 2286 from 2390, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
1040 divided by 381 is 2 with a remainder of 278.
Use 2 as the next digit of our solution. 
Result so far: 174896.162
Subtracting 762 from 1040 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 12:
381 can be fit into 2780 7 times, resulting in a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 174896.1627
If we take 2667 away from 2780, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 13:
381 can be fit into 1130 2 times, resulting in a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 174896.16272
If we take 762 away from 1130, we end up 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.

Step 14:
If we divide 3680 by 381, we get 9 and a remainder of 251.
The next digit of our result is 9. 
Result so far: 174896.162729
Subtract 3429 from 3680 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 15:
381 can be fit into 2510 6 times, resulting in a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 174896.1627296
Subtract 2286 from 2510 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 16:
The number 381 fits into 2240 5 times, leaving a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 174896.16272965
Subtract 1905 from 2240 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 174896.16272965, and the remainder is 3.35e-07.
