We're dividing 3700486 by 451 
We want to divide 3700486 by 451.

Going ahead to step 1:
If we divide 3 by 451, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 451

Moving on to step 2:
37 divided by 451 is 0 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.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 451

Moving on to step 3:
370 divided by 451 is 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 370 to get 370.
Grab the next digit (0) from the dividend, add it to 370, then carry on: 3700 / 451

Moving on to step 4:
When dividing 3700 by 451, we get 8 with a remainder of 92.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 3608 from 3700, we get 92.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 451

Moving on to step 5:
The number 451 fits into 924 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 902 away from 924, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 451

Step 6:
If we divide 228 by 451, we get 0 and a remainder of 228.
Put 0 as the next digit of the answer. 
Result so far: 820.0
Deduct 0 from 228 and we're left with 228.
Take the next digit (6) from the dividend and append it to 228, then repeat: 2286 / 451

On to step 7:
The number 451 fits into 2286 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 8205.0
The remainder is 31 after subtracting 2255 from 2286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
If we divide 310 by 451, we get 0 and a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 8205.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 9:
The number 451 fits into 3100 6 times, leaving a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 8205.06
Subtracting 2706 from 3100 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 10:
451 goes into 3940 8 times with a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 8205.068
If we take 3608 away from 3940, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
451 goes into 3320 7 times with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 8205.0687
The remainder is 163 after subtracting 3157 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 12:
The number 451 fits into 1630 3 times, leaving a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 8205.06873
If we take 1353 away from 1630, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 13:
If we divide 2770 by 451, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 8205.068736
The remainder is 64 after subtracting 2706 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
451 can be fit into 640 1 times, resulting in a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 8205.0687361
Subtracting 451 from 640 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 15:
When dividing 1890 by 451, we get 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 8205.06873614
Deduct 1804 from 1890 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 8205.06873614 with a balance of 8.6e-08.
