We look at the division of 3720651 by 438 
Let's see how many times 438 fits into 3720651.

On to step 1:
If we divide 3 by 438, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 438

Let's proceed to step 2:
438 goes into 37 0 times with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 438

Moving on to step 3:
438 goes into 372 0 times with a remainder of 372.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 372, we get 372.
Grab the next digit (0) from the dividend, add it to 372, then carry on: 3720 / 438

Moving on to step 4:
3720 divided by 438 is 8 with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 216 after subtracting 3504 from 3720.
Include the next digit (6) from the dividend after 216, then repeat: 2166 / 438

Step 5:
If we divide 2166 by 438, we get 4 and a remainder of 414.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 1752 from 2166 to get 414.
Bring next digit (5) of the dividend behind the 414 and repeat the process: 4145 / 438

On to step 6:
The number 438 fits into 4145 9 times, leaving a remainder of 203.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
If we take 3942 away from 4145, we end up with 203.
Include the next digit (1) from the dividend after 203, then repeat: 2031 / 438

On to step 7:
438 goes into 2031 4 times with a remainder of 279.
Write down 4 as next digit of the result. 
Result so far: 8494.0
Deduct 1752 from 2031 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 8:
438 can be fit into 2790 6 times, resulting in a remainder of 162.
The next digit of our result is 6. 
Result so far: 8494.6
Subtracting 2628 from 2790 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 9:
438 can be fit into 1620 3 times, resulting in a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 8494.63
Subtract 1314 from 1620 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 10:
When dividing 3060 by 438, we get 6 with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 8494.636
If we take 2628 away from 3060, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 11:
When dividing 4320 by 438, we get 9 with a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 8494.6369
Subtracting 3942 from 4320 leaves us 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.

Advancing to step 12:
The number 438 fits into 3780 8 times, leaving a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 8494.63698
Subtracting 3504 from 3780 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 13:
2760 divided by 438 is 6 with a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 8494.636986
The remainder is 132 after subtracting 2628 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 14:
1320 divided by 438 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 8494.6369863
Subtract 1314 from 1320 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 15:
The number 438 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8494.6369863
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 8494.6369863, and the remainder is 6e-08.
