We're dividing 45351345 by 70 
We're looking to find how many times 70 goes into 45351345.

Advancing to step 1:
70 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 70

Moving on to step 2:
If we divide 45 by 70, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 70

Moving on to step 3:
70 goes into 453 6 times with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 420 away from 453, we end up with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 70

Going ahead to step 4:
If we divide 335 by 70, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 280 from 335 to get 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 70

Going ahead to step 5:
The number 70 fits into 551 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 647.0
If we take 490 away from 551, we end up with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 70

Going ahead to step 6:
70 can be fit into 613 8 times, resulting in a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 6478.0
Deduct 560 from 613 and we're left with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 70

Moving on to step 7:
When dividing 534 by 70, we get 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 64787.0
Deduct 490 from 534 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 70

On to step 8:
If we divide 445 by 70, we get 6 and a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 647876.0
Deduct 420 from 445 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
250 divided by 70 is 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 647876.3
If we subtract 210 from 250, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 647876.35
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 70, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 647876.357
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 647876.3571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 647876.35714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 647876.357142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 647876.3571428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 647876.35714285
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 647876.35714285, with a leftover of 5e-08.
