We look at the division of 3951045 by 203 
We want to figure out the number of times 3951045 can be divided by 203.

On to step 1:
If we divide 3 by 203, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 203

Let's proceed to step 2:
203 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 203

Step 3:
When dividing 395 by 203, we get 1 with a remainder of 192.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 192 after subtracting 203 from 395.
Fetch the next digit (1) from the dividend, attach it to 192 and continue: 1921 / 203

On to step 4:
203 can be fit into 1921 9 times, resulting in a remainder of 94.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 1827 from 1921 to get 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 203

On to step 5:
940 divided by 203 is 4 with a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 194.0
If we take 812 away from 940, we end up with 128.
Bring next digit (4) of the dividend behind the 128 and repeat the process: 1284 / 203

Moving on to step 6:
203 goes into 1284 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 1946.0
The remainder is 66 after subtracting 1218 from 1284.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 203

Step 7:
203 goes into 665 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 19463.0
Subtracting 609 from 665 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
203 can be fit into 560 2 times, resulting in a remainder of 154.
The next digit of our result is 2. 
Result so far: 19463.2
Subtract 406 from 560 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 9:
203 can be fit into 1540 7 times, resulting in a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 19463.27
If we take 1421 away from 1540, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 10:
When dividing 1190 by 203, we get 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 19463.275
Deduct 1015 from 1190 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
The number 203 fits into 1750 8 times, leaving a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 19463.2758
Subtracting 1624 from 1750 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 12:
1260 divided by 203 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 19463.27586
Subtract 1218 from 1260 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
When dividing 420 by 203, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 19463.275862
Deduct 406 from 420 and we're left with 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 14:
203 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 19463.275862
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
203 goes into 1400 6 times with a remainder of 182.
The number 6 becomes the next digit in our result. 
Result so far: 19463.27586206
Subtracting 1218 from 1400 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 19463.27586206, with a leftover of 1.82e-07.
