Let's divide 45531855 by 345
We want to divide 45531855 by 345.

Moving on to step 1:
If we divide 4 by 345, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 345

Going ahead to step 2:
45 divided by 345 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 345

Advancing to step 3:
345 can be fit into 455 1 times, resulting in a remainder of 110.
The next digit of our result is 1. 
Result so far: 1.0
If we take 345 away from 455, we end up with 110.
Fetch the next digit (3) from the dividend, attach it to 110 and continue: 1103 / 345

On to step 4:
When dividing 1103 by 345, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1035 from 1103 to get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 345

Let's proceed to step 5:
When dividing 681 by 345, we get 1 with a remainder of 336.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 345 from 681 to get 336.
Append the next digit (8) from the dividend to 336 and continue with: 3368 / 345

Step 6:
If we divide 3368 by 345, we get 9 and a remainder of 263.
The next digit of our result is 9. 
Result so far: 1319.0
Deduct 3105 from 3368 and we're left with 263.
Bring next digit (5) of the dividend behind the 263 and repeat the process: 2635 / 345

Step 7:
The number 345 fits into 2635 7 times, leaving a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 13197.0
Subtracting 2415 from 2635 leaves us with 220.
Grab the next digit (5) from the dividend, add it to 220, then carry on: 2205 / 345

On to step 8:
If we divide 2205 by 345, we get 6 and a remainder of 135.
Put 6 as the next digit of the answer. 
Result so far: 131976.0
Subtracting 2070 from 2205 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 9:
1350 divided by 345 is 3 with a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 131976.3
Subtract 1035 from 1350 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 10:
345 goes into 3150 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 131976.39
If we subtract 3105 from 3150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
345 can be fit into 450 1 times, resulting in a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 131976.391
Subtracting 345 from 450 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 12:
1050 divided by 345 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 131976.3913
If we take 1035 away from 1050, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
150 divided by 345 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 131976.3913
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
345 goes into 1500 4 times with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 131976.391304
If we subtract 1380 from 1500, 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.

Advancing to step 15:
1200 divided by 345 is 3 with a remainder of 165.
Record the quotient 3 as the next digit in the result. 
Result so far: 131976.3913043
The remainder is 165 after subtracting 1035 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 16:
When dividing 1650 by 345, we get 4 with a remainder of 270.
The number 4 becomes the next digit in our result. 
Result so far: 131976.39130434
If we take 1380 away from 1650, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 131976.39130434, with a leftover of 2.7e-07.
