43974156 ÷ 279 
Our goal is to divide 43974156 by 279.

Moving on to step 1:
279 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 279

Advancing to step 2:
When dividing 43 by 279, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 279

Let's proceed to step 3:
When dividing 439 by 279, we get 1 with a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 279 from 439, we get 160.
Grab the next digit (7) from the dividend, add it to 160, then carry on: 1607 / 279

Step 4:
The number 279 fits into 1607 5 times, leaving a remainder of 212.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 1395 from 1607, we get 212.
Take the next digit (4) from the dividend and append it to 212, then repeat: 2124 / 279

Going ahead to step 5:
2124 divided by 279 is 7 with a remainder of 171.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we take 1953 away from 2124, we end up with 171.
Append the next digit (1) from the dividend to 171 and continue with: 1711 / 279

On to step 6:
The number 279 fits into 1711 6 times, leaving a remainder of 37.
The next digit of our result is 6. 
Result so far: 1576.0
If we subtract 1674 from 1711, we get 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 279

Advancing to step 7:
279 can be fit into 375 1 times, resulting in a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 15761.0
The remainder is 96 after subtracting 279 from 375.
Bring next digit (6) of the dividend behind the 96 and repeat the process: 966 / 279

Let's proceed to step 8:
966 divided by 279 is 3 with a remainder of 129.
Put 3 as the next digit of the answer. 
Result so far: 157613.0
If we subtract 837 from 966, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
279 goes into 1290 4 times with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 157613.4
If we take 1116 away from 1290, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
If we divide 1740 by 279, we get 6 and a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 157613.46
The remainder is 66 after subtracting 1674 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 279, we get 2 and a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 157613.462
Subtracting 558 from 660 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
If we divide 1020 by 279, we get 3 and a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 157613.4623
Deduct 837 from 1020 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 13:
279 goes into 1830 6 times with a remainder of 156.
The next digit of our result is 6. 
Result so far: 157613.46236
If we take 1674 away from 1830, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
279 can be fit into 1560 5 times, resulting in a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 157613.462365
If we subtract 1395 from 1560, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 15:
The number 279 fits into 1650 5 times, leaving a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 157613.4623655
If we take 1395 away from 1650, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 157613.4623655 with a remainder of 2.55e-06.
