1257643 divided by 356 
Let's see how many times 356 fits into 1257643.

Moving on to step 1:
When dividing 1 by 356, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 356

Going ahead to step 2:
The number 356 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 356

Advancing to step 3:
356 can be fit into 125 0 times, resulting in a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 356

Advancing to step 4:
356 goes into 1257 3 times with a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1068 from 1257 to get 189.
Append the next digit (6) from the dividend to 189 and continue with: 1896 / 356

Step 5:
356 can be fit into 1896 5 times, resulting in a remainder of 116.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 1780 from 1896 and we're left with 116.
Take the next digit (4) from the dividend and append it to 116, then repeat: 1164 / 356

Going ahead to step 6:
When dividing 1164 by 356, we get 3 with a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 353.0
The remainder is 96 after subtracting 1068 from 1164.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 356

On to step 7:
The number 356 fits into 963 2 times, leaving a remainder of 251.
Write down 2 as next digit of the result. 
Result so far: 3532.0
Subtract 712 from 963 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 8:
If we divide 2510 by 356, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3532.7
If we subtract 2492 from 2510, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 356, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 3532.7
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
1800 divided by 356 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 3532.705
Subtract 1780 from 1800 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
356 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 3532.705
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
356 goes into 2000 5 times with a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 3532.70505
If we take 1780 away from 2000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
2200 divided by 356 is 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 3532.705056
Subtracting 2136 from 2200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
356 goes into 640 1 times with a remainder of 284.
Record the quotient 1 as the next digit in the result. 
Result so far: 3532.7050561
Subtracting 356 from 640 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 15:
2840 divided by 356 is 7 with a remainder of 348.
Record the quotient 7 as the next digit in the result. 
Result so far: 3532.70505617
Deduct 2492 from 2840 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Our division results in 3532.70505617 with a remaining 3.48e-07.
