We're dividing 1397558 by 354 
We want to figure out the number of times 1397558 can be divided by 354.

Let's proceed to step 1:
The number 354 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 354

Moving on to step 2:
354 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 354

Moving on to step 3:
354 can be fit into 139 0 times, resulting in a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 354

Going ahead to step 4:
When dividing 1397 by 354, we get 3 with a remainder of 335.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1062 from 1397 to get 335.
Grab the next digit (5) from the dividend, add it to 335, then carry on: 3355 / 354

Going ahead to step 5:
If we divide 3355 by 354, we get 9 and a remainder of 169.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 3186 from 3355 leaves us with 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 354

Going ahead to step 6:
If we divide 1695 by 354, we get 4 and a remainder of 279.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Deduct 1416 from 1695 and we're left with 279.
Bring next digit (8) of the dividend behind the 279 and repeat the process: 2798 / 354

Going ahead to step 7:
If we divide 2798 by 354, we get 7 and a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 3947.0
Subtracting 2478 from 2798 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 8:
354 can be fit into 3200 9 times, resulting in a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 3947.9
Deduct 3186 from 3200 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.

On to step 9:
354 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 3947.9
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
1400 divided by 354 is 3 with a remainder of 338.
The number 3 becomes the next digit in our result. 
Result so far: 3947.903
If we subtract 1062 from 1400, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 11:
The number 354 fits into 3380 9 times, leaving a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 3947.9039
The remainder is 194 after subtracting 3186 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 12:
1940 divided by 354 is 5 with a remainder of 170.
The next digit of our result is 5. 
Result so far: 3947.90395
If we take 1770 away from 1940, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
354 can be fit into 1700 4 times, resulting in a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 3947.903954
The remainder is 284 after subtracting 1416 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 14:
If we divide 2840 by 354, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 3947.9039548
Subtract 2832 from 2840 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
80 divided by 354 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 3947.9039548
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 3947.9039548 and a remainder of 8e-08.
