We're dividing 43351518 by 803 
We want to divide 43351518 by 803.

Going ahead to step 1:
803 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 803

Let's proceed to step 2:
The number 803 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 803

Advancing to step 3:
803 can be fit into 433 0 times, resulting in a remainder of 433.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 433 to get 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 803

Moving on to step 4:
The number 803 fits into 4335 5 times, leaving a remainder of 320.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 320 after subtracting 4015 from 4335.
Bring next digit (1) of the dividend behind the 320 and repeat the process: 3201 / 803

Step 5:
803 can be fit into 3201 3 times, resulting in a remainder of 792.
Write down 3 as next digit of the result. 
Result so far: 53.0
Deduct 2409 from 3201 and we're left with 792.
Take the next digit (5) from the dividend and append it to 792, then repeat: 7925 / 803

Going ahead to step 6:
The number 803 fits into 7925 9 times, leaving a remainder of 698.
Write down 9 as next digit of the result. 
Result so far: 539.0
Deduct 7227 from 7925 and we're left with 698.
Grab the next digit (1) from the dividend, add it to 698, then carry on: 6981 / 803

Moving on to step 7:
803 goes into 6981 8 times with a remainder of 557.
The next digit of our result is 8. 
Result so far: 5398.0
Deduct 6424 from 6981 and we're left with 557.
Fetch the next digit (8) from the dividend, attach it to 557 and continue: 5578 / 803

Moving on to step 8:
The number 803 fits into 5578 6 times, leaving a remainder of 760.
Write down 6 as next digit of the result. 
Result so far: 53986.0
The remainder is 760 after subtracting 4818 from 5578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 9:
803 can be fit into 7600 9 times, resulting in a remainder of 373.
Record the quotient 9 as the next digit in the result. 
Result so far: 53986.9
If we take 7227 away from 7600, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 10:
803 can be fit into 3730 4 times, resulting in a remainder of 518.
The next digit of our result is 4. 
Result so far: 53986.94
The remainder is 518 after subtracting 3212 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 11:
When dividing 5180 by 803, we get 6 with a remainder of 362.
Use 6 as the next digit of our solution. 
Result so far: 53986.946
If we take 4818 away from 5180, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 12:
If we divide 3620 by 803, we get 4 and a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 53986.9464
The remainder is 408 after subtracting 3212 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 13:
If we divide 4080 by 803, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 53986.94645
If we take 4015 away from 4080, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
When dividing 650 by 803, we get 0 with a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 53986.94645
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 15:
When dividing 6500 by 803, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 53986.9464508
If we take 6424 away from 6500, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 16:
760 divided by 803 is 0 with a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 53986.9464508
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 53986.9464508, with a leftover of 7.6e-07.
