We divide 66636106 by 431
Our goal is to divide 66636106 by 431.

On to step 1:
When dividing 6 by 431, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 431

On to step 2:
431 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 431

Let's proceed to step 3:
431 can be fit into 666 1 times, resulting in a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 431 from 666 leaves us with 235.
Bring next digit (3) of the dividend behind the 235 and repeat the process: 2353 / 431

Advancing to step 4:
431 goes into 2353 5 times with a remainder of 198.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2155 away from 2353, we end up with 198.
Take the next digit (6) from the dividend and append it to 198, then repeat: 1986 / 431

Advancing to step 5:
431 can be fit into 1986 4 times, resulting in a remainder of 262.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
The remainder is 262 after subtracting 1724 from 1986.
Append the next digit (1) from the dividend to 262 and continue with: 2621 / 431

Moving on to step 6:
2621 divided by 431 is 6 with a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 1546.0
Deduct 2586 from 2621 and we're left with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 431

Advancing to step 7:
The number 431 fits into 350 0 times, leaving a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 15460.0
Deduct 0 from 350 and we're left with 350.
Append the next digit (6) from the dividend to 350 and continue with: 3506 / 431

Advancing to step 8:
431 can be fit into 3506 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 154608.0
Deduct 3448 from 3506 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
The number 431 fits into 580 1 times, leaving a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 154608.1
Subtracting 431 from 580 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 10:
The number 431 fits into 1490 3 times, leaving a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 154608.13
If we take 1293 away from 1490, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 11:
If we divide 1970 by 431, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 154608.134
If we subtract 1724 from 1970, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 12:
2460 divided by 431 is 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 154608.1345
If we take 2155 away from 2460, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 13:
431 can be fit into 3050 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 154608.13457
The remainder is 33 after subtracting 3017 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
330 divided by 431 is 0 with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 154608.13457
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 15:
431 goes into 3300 7 times with a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 154608.1345707
Deduct 3017 from 3300 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 16:
If we divide 2830 by 431, we get 6 and a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 154608.13457076
Subtract 2586 from 2830 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 154608.13457076 with a remainder of 2.44e-07.
