We're dividing 70145447 by 451 
We want to divide 70145447 by 451.

On to step 1:
When dividing 7 by 451, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 451

Let's proceed to step 2:
451 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 451

Let's proceed to step 3:
When dividing 701 by 451, we get 1 with a remainder of 250.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 451 from 701 to get 250.
Bring next digit (4) of the dividend behind the 250 and repeat the process: 2504 / 451

Advancing to step 4:
If we divide 2504 by 451, we get 5 and a remainder of 249.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 249 after subtracting 2255 from 2504.
Fetch the next digit (5) from the dividend, attach it to 249 and continue: 2495 / 451

On to step 5:
The number 451 fits into 2495 5 times, leaving a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 2255 from 2495 to get 240.
Fetch the next digit (4) from the dividend, attach it to 240 and continue: 2404 / 451

On to step 6:
If we divide 2404 by 451, we get 5 and a remainder of 149.
The number 5 becomes the next digit in our result. 
Result so far: 1555.0
Subtracting 2255 from 2404 leaves us with 149.
Bring next digit (4) of the dividend behind the 149 and repeat the process: 1494 / 451

Let's proceed to step 7:
When dividing 1494 by 451, we get 3 with a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 15553.0
Subtracting 1353 from 1494 leaves us with 141.
Bring next digit (7) of the dividend behind the 141 and repeat the process: 1417 / 451

Advancing to step 8:
If we divide 1417 by 451, we get 3 and a remainder of 64.
The next digit of our result is 3. 
Result so far: 155533.0
The remainder is 64 after subtracting 1353 from 1417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
451 can be fit into 640 1 times, resulting in a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 155533.1
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.

On to step 10:
If we divide 1890 by 451, we get 4 and a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 155533.14
Subtract 1804 from 1890 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
860 divided by 451 is 1 with a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 155533.141
If we take 451 away from 860, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 12:
When dividing 4090 by 451, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 155533.1419
The remainder is 31 after subtracting 4059 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
If we divide 310 by 451, we get 0 and a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 155533.1419
If we take 0 away from 310, we end up 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.

Going ahead to step 14:
451 can be fit into 3100 6 times, resulting in a remainder of 394.
The number 6 becomes the next digit in our result. 
Result so far: 155533.141906
The remainder is 394 after subtracting 2706 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 15:
451 can be fit into 3940 8 times, resulting in a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 155533.1419068
Subtract 3608 from 3940 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 16:
3320 divided by 451 is 7 with a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 155533.14190687
Subtract 3157 from 3320 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The quotient of the division is 155533.14190687, and the remainder is 1.63e-07.
