We're dividing 45162142 by 407 
We want to divide 45162142 by 407.

Step 1:
If we divide 4 by 407, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 407

Let's proceed to step 2:
45 divided by 407 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 407

Let's proceed to step 3:
If we divide 451 by 407, we get 1 and a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 407 from 451 to get 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 407

Moving on to step 4:
If we divide 446 by 407, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 39 after subtracting 407 from 446.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 407

Advancing to step 5:
407 goes into 392 0 times with a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtracting 0 from 392 leaves us with 392.
Grab the next digit (1) from the dividend, add it to 392, then carry on: 3921 / 407

Let's proceed to step 6:
When dividing 3921 by 407, we get 9 with a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 1109.0
Subtracting 3663 from 3921 leaves us with 258.
Bring next digit (4) of the dividend behind the 258 and repeat the process: 2584 / 407

Step 7:
When dividing 2584 by 407, we get 6 with a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 11096.0
If we take 2442 away from 2584, we end up with 142.
Bring next digit (2) of the dividend behind the 142 and repeat the process: 1422 / 407

On to step 8:
407 can be fit into 1422 3 times, resulting in a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 110963.0
Subtract 1221 from 1422 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 9:
If we divide 2010 by 407, we get 4 and a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 110963.4
Subtracting 1628 from 2010 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
3820 divided by 407 is 9 with a remainder of 157.
Record the quotient 9 as the next digit in the result. 
Result so far: 110963.49
The remainder is 157 after subtracting 3663 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 11:
The number 407 fits into 1570 3 times, leaving a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 110963.493
Deduct 1221 from 1570 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 12:
407 goes into 3490 8 times with a remainder of 234.
Use 8 as the next digit of our solution. 
Result so far: 110963.4938
Subtracting 3256 from 3490 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 13:
If we divide 2340 by 407, we get 5 and a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 110963.49385
Subtracting 2035 from 2340 leaves us 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.

Advancing to step 14:
If we divide 3050 by 407, we get 7 and a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 110963.493857
Subtracting 2849 from 3050 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 15:
If we divide 2010 by 407, we get 4 and a remainder of 382.
Put 4 as the next digit of the answer. 
Result so far: 110963.4938574
Deduct 1628 from 2010 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 16:
407 goes into 3820 9 times with a remainder of 157.
Put 9 as the next digit of the answer. 
Result so far: 110963.49385749
Subtracting 3663 from 3820 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.

The final outcome is 110963.49385749, with a leftover of 1.57e-07.
