Let's divide 45212019 by 43
We want to divide 45212019 by 43.

Let's proceed to step 1:
If we divide 4 by 43, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 43

Let's proceed to step 2:
43 goes into 45 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 43 from 45 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 43

Advancing to step 3:
43 can be fit into 22 0 times, resulting in a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 43

Let's proceed to step 4:
43 goes into 221 5 times with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Deduct 215 from 221 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 43

Let's proceed to step 5:
When dividing 62 by 43, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
If we subtract 43 from 62, we get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 43

Moving on to step 6:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 10514.0
The remainder is 18 after subtracting 172 from 190.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 43

On to step 7:
The number 43 fits into 181 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 105144.0
If we take 172 away from 181, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 43

Step 8:
If we divide 99 by 43, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 1051442.0
If we subtract 86 from 99, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
If we divide 130 by 43, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1051442.3
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
10 divided by 43 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1051442.3
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 1051442.302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
43 goes into 140 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 1051442.3023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
If we divide 110 by 43, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1051442.30232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 43 fits into 240 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 1051442.302325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
43 goes into 250 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1051442.3023255
Subtracting 215 from 250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 1051442.3023255 with a remainder of 3.5e-07.
