We look at the division of 63791164 by 620 
We want to figure out the number of times 63791164 can be divided by 620.

Step 1:
The number 620 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 620

Going ahead to step 2:
620 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 620

Advancing to step 3:
637 divided by 620 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 620 from 637 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 620

Going ahead to step 4:
When dividing 179 by 620, we get 0 with a remainder of 179.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 179 after subtracting 0 from 179.
Bring next digit (1) of the dividend behind the 179 and repeat the process: 1791 / 620

Step 5:
If we divide 1791 by 620, we get 2 and a remainder of 551.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 1240 from 1791 leaves us with 551.
Grab the next digit (1) from the dividend, add it to 551, then carry on: 5511 / 620

Step 6:
620 goes into 5511 8 times with a remainder of 551.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
The remainder is 551 after subtracting 4960 from 5511.
Append the next digit (6) from the dividend to 551 and continue with: 5516 / 620

Going ahead to step 7:
When dividing 5516 by 620, we get 8 with a remainder of 556.
Use 8 as the next digit of our solution. 
Result so far: 10288.0
If we take 4960 away from 5516, we end up with 556.
Fetch the next digit (4) from the dividend, attach it to 556 and continue: 5564 / 620

Going ahead to step 8:
When dividing 5564 by 620, we get 8 with a remainder of 604.
The number 8 becomes the next digit in our result. 
Result so far: 102888.0
If we take 4960 away from 5564, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 9:
When dividing 6040 by 620, we get 9 with a remainder of 460.
Use 9 as the next digit of our solution. 
Result so far: 102888.9
If we subtract 5580 from 6040, we 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.

Advancing to step 10:
If we divide 4600 by 620, we get 7 and a remainder of 260.
The next digit of our result is 7. 
Result so far: 102888.97
Subtract 4340 from 4600 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
When dividing 2600 by 620, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 102888.974
Deduct 2480 from 2600 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
If we divide 1200 by 620, we get 1 and a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 102888.9741
Subtract 620 from 1200 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 13:
If we divide 5800 by 620, we get 9 and a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 102888.97419
Deduct 5580 from 5800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
When dividing 2200 by 620, we get 3 with a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 102888.974193
Deduct 1860 from 2200 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 15:
620 can be fit into 3400 5 times, resulting in a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 102888.9741935
Subtracting 3100 from 3400 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 16:
620 goes into 3000 4 times with a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 102888.97419354
If we take 2480 away from 3000, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 102888.97419354 with a remaining 5.2e-07.
