We're dividing 70803537 by 172 
We want to divide 70803537 by 172.

Step 1:
The number 172 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 172

Advancing to step 2:
172 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 172

On to step 3:
172 can be fit into 708 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 688 from 708 to get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 172

Advancing to step 4:
172 goes into 200 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 28 after subtracting 172 from 200.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 172

Moving on to step 5:
When dividing 283 by 172, we get 1 with a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
If we take 172 away from 283, we end up with 111.
Grab the next digit (5) from the dividend, add it to 111, then carry on: 1115 / 172

Advancing to step 6:
172 goes into 1115 6 times with a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 4116.0
Deduct 1032 from 1115 and we're left with 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 172

Let's proceed to step 7:
833 divided by 172 is 4 with a remainder of 145.
Put 4 as the next digit of the answer. 
Result so far: 41164.0
Deduct 688 from 833 and we're left with 145.
Include the next digit (7) from the dividend after 145, then repeat: 1457 / 172

On to step 8:
If we divide 1457 by 172, we get 8 and a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 411648.0
Subtract 1376 from 1457 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
If we divide 810 by 172, we get 4 and a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 411648.4
The remainder is 122 after subtracting 688 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
172 goes into 1220 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 411648.47
If we take 1204 away from 1220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 172, we get 0 and a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 411648.47
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
The number 172 fits into 1600 9 times, leaving a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 411648.4709
If we subtract 1548 from 1600, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
172 can be fit into 520 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 411648.47093
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
172 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 411648.47093
If we subtract 0 from 40, 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.

Step 15:
The number 172 fits into 400 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 411648.4709302
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 16:
If we divide 560 by 172, we get 3 and a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 411648.47093023
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 411648.47093023 and a remainder of 4.4e-08.
