43600956 ÷ 861 
We want to divide 43600956 by 861.

Step 1:
If we divide 4 by 861, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 861

On to step 2:
861 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 861

Step 3:
861 goes into 436 0 times with a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 436 to get 436.
Take the next digit (0) from the dividend and append it to 436, then repeat: 4360 / 861

Advancing to step 4:
861 can be fit into 4360 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4305 from 4360, we get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 861

Moving on to step 5:
550 divided by 861 is 0 with a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 550 after subtracting 0 from 550.
Take the next digit (9) from the dividend and append it to 550, then repeat: 5509 / 861

Going ahead to step 6:
5509 divided by 861 is 6 with a remainder of 343.
The next digit of our result is 6. 
Result so far: 506.0
If we subtract 5166 from 5509, we get 343.
Include the next digit (5) from the dividend after 343, then repeat: 3435 / 861

Let's proceed to step 7:
When dividing 3435 by 861, we get 3 with a remainder of 852.
The number 3 becomes the next digit in our result. 
Result so far: 5063.0
Deduct 2583 from 3435 and we're left with 852.
Include the next digit (6) from the dividend after 852, then repeat: 8526 / 861

Going ahead to step 8:
861 can be fit into 8526 9 times, resulting in a remainder of 777.
The number 9 becomes the next digit in our result. 
Result so far: 50639.0
Deduct 7749 from 8526 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Let's proceed to step 9:
861 goes into 7770 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 50639.9
The remainder is 21 after subtracting 7749 from 7770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
If we divide 210 by 861, we get 0 and a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 50639.9
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 11:
861 can be fit into 2100 2 times, resulting in a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 50639.902
Deduct 1722 from 2100 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 12:
If we divide 3780 by 861, we get 4 and a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 50639.9024
Subtract 3444 from 3780 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
The number 861 fits into 3360 3 times, leaving a remainder of 777.
Write down 3 as next digit of the result. 
Result so far: 50639.90243
Deduct 2583 from 3360 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 14:
7770 divided by 861 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 50639.902439
Deduct 7749 from 7770 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 15:
The number 861 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 50639.902439
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 16:
If we divide 2100 by 861, we get 2 and a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 50639.90243902
Subtract 1722 from 2100 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The quotient of the division is 50639.90243902, and the remainder is 3.78e-07.
