3961538 ÷ 862 
We want to figure out the number of times 3961538 can be divided by 862.

Moving on to step 1:
The number 862 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 862

Moving on to step 2:
862 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 862

Advancing to step 3:
396 divided by 862 is 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Bring next digit (1) of the dividend behind the 396 and repeat the process: 3961 / 862

Step 4:
3961 divided by 862 is 4 with a remainder of 513.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 513 after subtracting 3448 from 3961.
Grab the next digit (5) from the dividend, add it to 513, then carry on: 5135 / 862

Step 5:
The number 862 fits into 5135 5 times, leaving a remainder of 825.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 4310 from 5135 leaves us with 825.
Bring next digit (3) of the dividend behind the 825 and repeat the process: 8253 / 862

Moving on to step 6:
8253 divided by 862 is 9 with a remainder of 495.
Write down 9 as next digit of the result. 
Result so far: 459.0
If we subtract 7758 from 8253, we get 495.
Fetch the next digit (8) from the dividend, attach it to 495 and continue: 4958 / 862

Going ahead to step 7:
862 goes into 4958 5 times with a remainder of 648.
The number 5 becomes the next digit in our result. 
Result so far: 4595.0
Subtracting 4310 from 4958 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 8:
862 goes into 6480 7 times with a remainder of 446.
Put 7 as the next digit of the answer. 
Result so far: 4595.7
If we subtract 6034 from 6480, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 9:
The number 862 fits into 4460 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 4595.75
If we subtract 4310 from 4460, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
If we divide 1500 by 862, we get 1 and a remainder of 638.
Put 1 as the next digit of the answer. 
Result so far: 4595.751
The remainder is 638 after subtracting 862 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 11:
862 can be fit into 6380 7 times, resulting in a remainder of 346.
The number 7 becomes the next digit in our result. 
Result so far: 4595.7517
The remainder is 346 after subtracting 6034 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 12:
3460 divided by 862 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4595.75174
If we take 3448 away from 3460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 862 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 4595.75174
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
862 can be fit into 1200 1 times, resulting in a remainder of 338.
The next digit of our result is 1. 
Result so far: 4595.7517401
If we subtract 862 from 1200, 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.

Moving on to step 15:
If we divide 3380 by 862, we get 3 and a remainder of 794.
Put 3 as the next digit of the answer. 
Result so far: 4595.75174013
Subtract 2586 from 3380 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

The final outcome is 4595.75174013, with a leftover of 7.94e-07.
