45391734 divided by 402 
Our goal is to divide 45391734 by 402.

Advancing to step 1:
4 divided by 402 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 402

On to step 2:
When dividing 45 by 402, we get 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.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 402

On to step 3:
402 goes into 453 1 times with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 402 from 453 leaves us with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 402

On to step 4:
519 divided by 402 is 1 with a remainder of 117.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 402 from 519 and we're left with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 402

On to step 5:
402 can be fit into 1171 2 times, resulting in a remainder of 367.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
The remainder is 367 after subtracting 804 from 1171.
Append the next digit (7) from the dividend to 367 and continue with: 3677 / 402

On to step 6:
402 can be fit into 3677 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
If we take 3618 away from 3677, we end up with 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 402

Step 7:
402 can be fit into 593 1 times, resulting in a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 11291.0
Subtracting 402 from 593 leaves us with 191.
Bring next digit (4) of the dividend behind the 191 and repeat the process: 1914 / 402

Going ahead to step 8:
The number 402 fits into 1914 4 times, leaving a remainder of 306.
The number 4 becomes the next digit in our result. 
Result so far: 112914.0
Subtract 1608 from 1914 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
3060 divided by 402 is 7 with a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 112914.7
Subtracting 2814 from 3060 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
402 goes into 2460 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 112914.76
Subtract 2412 from 2460 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
If we divide 480 by 402, we get 1 and a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 112914.761
The remainder is 78 after subtracting 402 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
402 can be fit into 780 1 times, resulting in a remainder of 378.
Write down 1 as next digit of the result. 
Result so far: 112914.7611
Deduct 402 from 780 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Our division results in 112914.7611 with a remaining 0.00378.
