We look at the division of 43878790 by 277 
We want to divide 43878790 by 277.

Moving on to step 1:
The number 277 fits into 4 0 times, leaving 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.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 277

Moving on to step 2:
277 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 277

Let's proceed to step 3:
438 divided by 277 is 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 161 after subtracting 277 from 438.
Fetch the next digit (7) from the dividend, attach it to 161 and continue: 1617 / 277

On to step 4:
277 goes into 1617 5 times with a remainder of 232.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 1385 away from 1617, we end up with 232.
Grab the next digit (8) from the dividend, add it to 232, then carry on: 2328 / 277

Advancing to step 5:
If we divide 2328 by 277, we get 8 and a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Deduct 2216 from 2328 and we're left with 112.
Bring next digit (7) of the dividend behind the 112 and repeat the process: 1127 / 277

Going ahead to step 6:
277 goes into 1127 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 1584.0
If we take 1108 away from 1127, we end up with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 277

On to step 7:
277 goes into 199 0 times with a remainder of 199.
The next digit of our result is 0. 
Result so far: 15840.0
Subtract 0 from 199 to get 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 277

Moving on to step 8:
If we divide 1990 by 277, we get 7 and a remainder of 51.
The next digit of our result is 7. 
Result so far: 158407.0
If we take 1939 away from 1990, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 277, we get 1 and a remainder of 233.
The next digit of our result is 1. 
Result so far: 158407.1
The remainder is 233 after subtracting 277 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 10:
277 can be fit into 2330 8 times, resulting in a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 158407.18
If we take 2216 away from 2330, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
When dividing 1140 by 277, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 158407.184
If we subtract 1108 from 1140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
277 goes into 320 1 times with a remainder of 43.
The next digit of our result is 1. 
Result so far: 158407.1841
If we take 277 away from 320, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
The number 277 fits into 430 1 times, leaving a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 158407.18411
Subtract 277 from 430 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The quotient of the division is 158407.18411, and the remainder is 0.000153.
