15615949 ÷ 354 
Our goal is to divide 15615949 by 354.

Step 1:
354 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 354

Step 2:
When dividing 15 by 354, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 354

Going ahead to step 3:
If we divide 156 by 354, we get 0 and a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Fetch the next digit (1) from the dividend, attach it to 156 and continue: 1561 / 354

Advancing to step 4:
1561 divided by 354 is 4 with a remainder of 145.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1416 from 1561 leaves us with 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 354

Going ahead to step 5:
354 goes into 1455 4 times with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 1416 from 1455, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 354

Step 6:
The number 354 fits into 399 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
Deduct 354 from 399 and we're left with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 354

On to step 7:
If we divide 454 by 354, we get 1 and a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 4411.0
If we subtract 354 from 454, we get 100.
Fetch the next digit (9) from the dividend, attach it to 100 and continue: 1009 / 354

On to step 8:
354 goes into 1009 2 times with a remainder of 301.
Record the quotient 2 as the next digit in the result. 
Result so far: 44112.0
If we take 708 away from 1009, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 9:
3010 divided by 354 is 8 with a remainder of 178.
Put 8 as the next digit of the answer. 
Result so far: 44112.8
If we take 2832 away from 3010, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
When dividing 1780 by 354, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 44112.85
The remainder is 10 after subtracting 1770 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 354, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 44112.85
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
The number 354 fits into 1000 2 times, leaving a remainder of 292.
Record the quotient 2 as the next digit in the result. 
Result so far: 44112.8502
Deduct 708 from 1000 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 13:
354 goes into 2920 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 44112.85028
Subtract 2832 from 2920 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
354 can be fit into 880 2 times, resulting in a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 44112.850282
If we subtract 708 from 880, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 15:
The number 354 fits into 1720 4 times, leaving a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 44112.8502824
Deduct 1416 from 1720 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 16:
If we divide 3040 by 354, we get 8 and a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 44112.85028248
If we subtract 2832 from 3040, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 44112.85028248 and a remainder of 2.08e-07.
