We look at the division of 72137943 by 620 
We want to figure out the number of times 72137943 can be divided by 620.

Going ahead to step 1:
When dividing 7 by 620, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 620

Going ahead to step 2:
If we divide 72 by 620, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 620

Let's proceed to step 3:
When dividing 721 by 620, we get 1 with a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 620 from 721 to get 101.
Fetch the next digit (3) from the dividend, attach it to 101 and continue: 1013 / 620

Advancing to step 4:
The number 620 fits into 1013 1 times, leaving a remainder of 393.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 620 from 1013, we get 393.
Grab the next digit (7) from the dividend, add it to 393, then carry on: 3937 / 620

Going ahead to step 5:
620 can be fit into 3937 6 times, resulting in a remainder of 217.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtracting 3720 from 3937 leaves us with 217.
Include the next digit (9) from the dividend after 217, then repeat: 2179 / 620

Going ahead to step 6:
620 can be fit into 2179 3 times, resulting in a remainder of 319.
The next digit of our result is 3. 
Result so far: 1163.0
The remainder is 319 after subtracting 1860 from 2179.
Include the next digit (4) from the dividend after 319, then repeat: 3194 / 620

Going ahead to step 7:
620 can be fit into 3194 5 times, resulting in a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 11635.0
If we subtract 3100 from 3194, we get 94.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 620

Going ahead to step 8:
620 can be fit into 943 1 times, resulting in a remainder of 323.
The next digit of our result is 1. 
Result so far: 116351.0
Deduct 620 from 943 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 9:
If we divide 3230 by 620, we get 5 and a remainder of 130.
The next digit of our result is 5. 
Result so far: 116351.5
If we subtract 3100 from 3230, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
620 goes into 1300 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 116351.52
The remainder is 60 after subtracting 1240 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 620 fits into 600 0 times, leaving a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 116351.52
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
620 goes into 6000 9 times with a remainder of 420.
The next digit of our result is 9. 
Result so far: 116351.5209
Deduct 5580 from 6000 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 13:
4200 divided by 620 is 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 116351.52096
If we take 3720 away from 4200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
620 goes into 4800 7 times with a remainder of 460.
Write down 7 as next digit of the result. 
Result so far: 116351.520967
Subtract 4340 from 4800 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 15:
When dividing 4600 by 620, we get 7 with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 116351.5209677
Subtracting 4340 from 4600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 116351.5209677, with a leftover of 2.6e-06.
