45131231 divided by 392 
We want to figure out the number of times 45131231 can be divided by 392.

Let's proceed to step 1:
The number 392 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 392

Advancing to step 2:
The number 392 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 392

Advancing to step 3:
392 goes into 451 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 392 away from 451, we end up with 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 392

Going ahead to step 4:
593 divided by 392 is 1 with a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 392 from 593, we get 201.
Append the next digit (1) from the dividend to 201 and continue with: 2011 / 392

Going ahead to step 5:
If we divide 2011 by 392, we get 5 and a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 51 after subtracting 1960 from 2011.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 392

On to step 6:
392 goes into 512 1 times with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1151.0
If we take 392 away from 512, we end up with 120.
Fetch the next digit (3) from the dividend, attach it to 120 and continue: 1203 / 392

Step 7:
1203 divided by 392 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 11513.0
Deduct 1176 from 1203 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 392

Step 8:
392 goes into 271 0 times with a remainder of 271.
The next digit of our result is 0. 
Result so far: 115130.0
If we take 0 away from 271, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
392 goes into 2710 6 times with a remainder of 358.
Put 6 as the next digit of the answer. 
Result so far: 115130.6
Subtracting 2352 from 2710 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 10:
392 can be fit into 3580 9 times, resulting in a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 115130.69
Subtract 3528 from 3580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
392 can be fit into 520 1 times, resulting in a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 115130.691
Deduct 392 from 520 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
392 can be fit into 1280 3 times, resulting in a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 115130.6913
Subtracting 1176 from 1280 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
When dividing 1040 by 392, we get 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 115130.69132
Subtract 784 from 1040 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 14:
392 goes into 2560 6 times with a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 115130.691326
If we take 2352 away from 2560, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
392 goes into 2080 5 times with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 115130.6913265
If we subtract 1960 from 2080, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
The number 392 fits into 1200 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 115130.69132653
If we subtract 1176 from 1200, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 115130.69132653, and the remainder is 2.4e-08.
