62906358 ÷ 840 
The aim is to understand the frequency of 840 in 62906358.

On to step 1:
If we divide 6 by 840, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 840

Going ahead to step 2:
The number 840 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 840

Step 3:
When dividing 629 by 840, we get 0 with a remainder of 629.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 629, we get 629.
Fetch the next digit (0) from the dividend, attach it to 629 and continue: 6290 / 840

Going ahead to step 4:
When dividing 6290 by 840, we get 7 with a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5880 away from 6290, we end up with 410.
Grab the next digit (6) from the dividend, add it to 410, then carry on: 4106 / 840

On to step 5:
4106 divided by 840 is 4 with a remainder of 746.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 3360 away from 4106, we end up with 746.
Include the next digit (3) from the dividend after 746, then repeat: 7463 / 840

Going ahead to step 6:
When dividing 7463 by 840, we get 8 with a remainder of 743.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
Subtract 6720 from 7463 to get 743.
Append the next digit (5) from the dividend to 743 and continue with: 7435 / 840

Advancing to step 7:
840 goes into 7435 8 times with a remainder of 715.
Use 8 as the next digit of our solution. 
Result so far: 7488.0
Deduct 6720 from 7435 and we're left with 715.
Include the next digit (8) from the dividend after 715, then repeat: 7158 / 840

Let's proceed to step 8:
If we divide 7158 by 840, we get 8 and a remainder of 438.
Use 8 as the next digit of our solution. 
Result so far: 74888.0
Subtract 6720 from 7158 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 9:
If we divide 4380 by 840, we get 5 and a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 74888.5
Subtracting 4200 from 4380 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
The number 840 fits into 1800 2 times, leaving a remainder of 120.
The next digit of our result is 2. 
Result so far: 74888.52
Subtracting 1680 from 1800 leaves us 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.

Let's proceed to step 11:
840 goes into 1200 1 times with a remainder of 360.
The next digit of our result is 1. 
Result so far: 74888.521
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
When dividing 3600 by 840, we get 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 74888.5214
If we take 3360 away from 3600, we end up 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.

Step 13:
2400 divided by 840 is 2 with a remainder of 720.
The number 2 becomes the next digit in our result. 
Result so far: 74888.52142
If we subtract 1680 from 2400, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 14:
7200 divided by 840 is 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 74888.521428
Subtracting 6720 from 7200 leaves us 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.

Moving on to step 15:
The number 840 fits into 4800 5 times, leaving a remainder of 600.
The next digit of our result is 5. 
Result so far: 74888.5214285
Subtract 4200 from 4800 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 16:
840 goes into 6000 7 times with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 74888.52142857
Subtracting 5880 from 6000 leaves us 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.

In conclusion, the division gives 74888.52142857 with a balance of 1.2e-07.
