We divide 63640220 by 172
We're looking to find how many times 172 goes into 63640220.

Let's proceed to step 1:
When dividing 6 by 172, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 172

Going ahead to step 2:
63 divided by 172 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 172

On to step 3:
172 can be fit into 636 3 times, resulting in a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 516 from 636 leaves us with 120.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 172

Moving on to step 4:
172 goes into 1204 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 1204 away from 1204, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 172

Advancing to step 5:
If we divide 0 by 172, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 370.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 172

On to step 6:
The number 172 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 3700.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 172

Moving on to step 7:
When dividing 22 by 172, we get 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 37000.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 172

Let's proceed to step 8:
When dividing 220 by 172, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 370001.0
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
When dividing 480 by 172, we get 2 with a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 370001.2
Subtracting 344 from 480 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
1360 divided by 172 is 7 with a remainder of 156.
Write down 7 as next digit of the result. 
Result so far: 370001.27
The remainder is 156 after subtracting 1204 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
If we divide 1560 by 172, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 370001.279
The remainder is 12 after subtracting 1548 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
The number 172 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 370001.279
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
When dividing 1200 by 172, we get 6 with a remainder of 168.
The next digit of our result is 6. 
Result so far: 370001.27906
Subtracting 1032 from 1200 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 14:
1680 divided by 172 is 9 with a remainder of 132.
Write down 9 as next digit of the result. 
Result so far: 370001.279069
Subtracting 1548 from 1680 leaves us with 132.
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 15:
The number 172 fits into 1320 7 times, leaving a remainder of 116.
The next digit of our result is 7. 
Result so far: 370001.2790697
The remainder is 116 after subtracting 1204 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 16:
When dividing 1160 by 172, we get 6 with a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 370001.27906976
If we take 1032 away from 1160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 370001.27906976, with a leftover of 1.28e-07.
