We're dividing 37721888 by 620 
The aim is to understand the frequency of 620 in 37721888.

On to step 1:
The number 620 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 620

Going ahead to step 2:
The number 620 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 620

Let's proceed to step 3:
When dividing 377 by 620, we get 0 with a remainder of 377.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 377 after subtracting 0 from 377.
Bring next digit (2) of the dividend behind the 377 and repeat the process: 3772 / 620

Going ahead to step 4:
620 goes into 3772 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 52 after subtracting 3720 from 3772.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 620

Going ahead to step 5:
When dividing 521 by 620, we get 0 with a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 521 leaves us with 521.
Include the next digit (8) from the dividend after 521, then repeat: 5218 / 620

Moving on to step 6:
The number 620 fits into 5218 8 times, leaving a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 608.0
Subtracting 4960 from 5218 leaves us with 258.
Bring next digit (8) of the dividend behind the 258 and repeat the process: 2588 / 620

On to step 7:
When dividing 2588 by 620, we get 4 with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 6084.0
If we take 2480 away from 2588, we end up with 108.
Bring next digit (8) of the dividend behind the 108 and repeat the process: 1088 / 620

Advancing to step 8:
620 can be fit into 1088 1 times, resulting in a remainder of 468.
Write down 1 as next digit of the result. 
Result so far: 60841.0
Subtracting 620 from 1088 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 9:
When dividing 4680 by 620, we get 7 with a remainder of 340.
The next digit of our result is 7. 
Result so far: 60841.7
Subtracting 4340 from 4680 leaves us 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 10:
620 goes into 3400 5 times with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 60841.75
Subtract 3100 from 3400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
3000 divided by 620 is 4 with a remainder of 520.
The next digit of our result is 4. 
Result so far: 60841.754
Deduct 2480 from 3000 and we're left 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.

Step 12:
620 can be fit into 5200 8 times, resulting in a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 60841.7548
Deduct 4960 from 5200 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
The number 620 fits into 2400 3 times, leaving a remainder of 540.
Put 3 as the next digit of the answer. 
Result so far: 60841.75483
Deduct 1860 from 2400 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
If we divide 5400 by 620, we get 8 and a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 60841.754838
Subtract 4960 from 5400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 15:
620 goes into 4400 7 times with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 60841.7548387
The remainder is 60 after subtracting 4340 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
When dividing 600 by 620, we get 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 60841.7548387
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 60841.7548387, and the remainder is 6e-07.
